TLS830A4EPV50XUMA1 Overview
An LDO (Low-Dropout) linear regulator is a class of voltage regulator that maintains a stable output voltage even when the input voltage is only marginally above the desired output. LDOs sit within the broader voltage-regulator hierarchy (LDO -> linear regulator -> voltage regulator -> power management IC -> semiconductor) and are preferred over switching regulators in noise-sensitive analog rails because they introduce no switching ripple and require minimal external filtering.
Key features include a typical quiescent current of only 4.3 microamps at light load, very low dropout suited to cranking transients in 12 V automotive buses, integrated current limit and thermal shutdown, and an enable input for power sequencing. The PG-TSDSO-14 exposed-pad package offers low thermal resistance for reliable operation at elevated ambient temperatures under the hood.
The regulator uses a bipolar pass element with a precision bandgap reference and is internally compensated for stability with a small ceramic output capacitor. Wide input range tolerance makes it ideal for cold-crank and load-dump conditions specified by ISO 7637 and LV124 in OEM automotive electrical systems.
Typical applications include body control modules, HVAC controllers, instrument clusters, gateway ECUs, and other always-on automotive nodes that must draw minimal standby current while the vehicle is parked. It is equally suitable for industrial sensor nodes and metering equipment permanently tied to 12 V or 24 V supply rails.
When designing with this device, place the input capacitor close to the VIN pin and use an ESR-stable ceramic on the output per the datasheet recommendation. Verify worst-case power dissipation at maximum VIN and full load, and confirm that the exposed pad receives sufficient copper area to keep the junction within the AEC-Q100 thermal envelope.

Typical Applications
TLS830A4EPV50XUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), HVAC Control Module, Instrument Cluster MCU Power, Automotive Gateway ECU, Industrial 24 V Sensor Node, Smart Metering / Always-On Battery Node.
Automotive Body Control Module (BCM)
The TLS830A4EPV50XUMA1 powers always-on logic inside body control modules that remain connected to the 12 V battery even when the vehicle is parked. Its 4.3 microamp typical quiescent current keeps standby drain well below OEM requirements of typically <100 microamp per node, while the 3.2 V to 40 V input tolerance handles cold-crank drops and 35 V load-dump transients per ISO 7637. Placed on the BCM's permanent-rail output, it supplies microcontroller wake-up circuitry and CAN/LIN transceivers with clean, ripple-free 5 V. The AEC-Q100 Grade 1 qualification to +150 C junction supports under-hood mounting, and the PG-TSDSO-14 exposed pad handles the worst-case 0.7 W dissipation at VIN=12 V / IOUT=300 mA with adequate copper pours.
Recommended
HVAC Control Module
In HVAC control modules the TLS830A4EPV50XUMA1 provides a quiet 5 V rail for the blower motor microcontroller and NTC temperature sensing front-end. Its ultra-low quiescent current is critical because HVAC modules may retain logic-power connectivity in 'key-off' states for cabin pre-conditioning and diagnostics. The wide 40 V input tolerance tolerates jump-start events and alternator load-dump spikes common on 12 V systems, while the low-dropout design retains regulation during engine cranking when battery voltage dips below 6 V. Mounted near the MCU, the regulator's exposed pad dissipates up to 0.7 W with proper thermal via stitching, keeping junction rise below +50 C even at +85 C ambient cabin temperatures typical of roof-console mounting.
Recommended
Instrument Cluster MCU Power
Instrument clusters demand a clean, ripple-free 5 V rail for the graphics MCU, stepper-motor gauge drivers, and CAN-FD transceiver. The TLS830A4EPV50XUMA1's LDO architecture introduces no switching noise that would corrupt the cluster's analog gauge drive or dimming PWM signals. Its AEC-Q100 Grade 1 rating supports the +125 C ambient temperatures inside the dashboard under direct sunlight, and the 4.3 microamp Iq is benign because the cluster is typically woken via CAN rather than held in standby. The exposed-pad PG-TSDSO-14 package fits behind the gauge cluster PCB with thermal vias into the inner copper plane, handling the ~0.5 W typical dissipation when the cluster runs at full brightness.
Recommended
Automotive Gateway ECU
Central gateway ECUs route CAN, CAN-FD, LIN, and Ethernet traffic between vehicle domains, requiring reliable 5 V rails for transceivers and microcontrollers. The TLS830A4EPV50XUMA1 supplies permanent-power rails inside the gateway that must remain alive even with the ignition off, supporting remote-firmware-update wake events and diagnostic retention. Its 40 V input range and load-dump immunity protect the gateway from transients induced by other high-current loads on the same battery bus. The PG-TSDSO-14 package simplifies layout near multi-rail DC-DC converters, where its low quiescent current contributes negligible standby loss. AEC-Q100 qualification is mandatory for OEM gateway reference designs and helps consolidate the BOM across vehicle programs.
Recommended
Industrial 24 V Sensor Node
Beyond automotive, the TLS830A4EPV50XUMA1 fits permanently-powered industrial 24 V sensor nodes such as pressure, level, or flow transmitters that must operate from the same supply as the PLC. Its 40 V maximum input handles 24 V industrial bus transients per IEC 61131-2, while the low Iq of 4.3 microamps extends battery-backed operation during mains failure. The LDO's clean output is ideal for powering 4-20 mA loop-side ADC references and HART modem front-ends, where switching ripple would inject errors into the loop current. Housed in a compact PG-TSDSO-14, it fits inside the sensor head's explosion-proof enclosure where PCB area is constrained.
Recommended
Smart Metering / Always-On Battery Node
Smart electricity, water, and gas meters run on lithium primary cells with multi-year service-life targets, demanding nanoamp-level standby consumption. The TLS830A4EPV50XUMA1's 4.3 microamp quiescent current keeps the meter's always-on metrology block alive between measurement intervals without depleting the battery. Its wide input range tolerates rectified mains-derived rails and battery stack voltages up to 40 V during the meter's full operational envelope. The AEC-Q100 pedigree gives utility customers confidence in long-term reliability even though the meter itself is not a moving-vehicle application. Combined with the exposed-pad PG-TSDSO-14, the regulator integrates cleanly into the meter's compact power module.

Key Differentiators
- Ultra-low 4.3 microamp quiescent current optimized for always-on battery nodes (vs TLS810B1LDV50XUMA1)
- Wide 3.2 V to 40 V input tolerance for cold-crank and load-dump survival (vs TLE4678ELXUMA2)
- Compact PG-TSDSO-14 with exposed pad for high-thermal-density PCBAs (vs TLE42062GXUMA2)
Design Notes
Estimated: at VIN = 12 V, VOUT = 5 V, and IOUT = 300 mA, the regulator dissipates approximately (12-5)*0.3 = 2.1 W. The PG-TSDSO-14 with a 1 square-inch copper pour on a 4-layer FR4 board typically achieves theta_JA near 35-40 C/W. To keep the junction below +150 C at +85 C ambient, designers should keep dissipation under 1.6 W and consider airflow or via-stitching into inner copper planes.
Place the input capacitor (typically 1 microfarat low-ESR ceramic) within 5 mm of the VIN pins, and connect the exposed thermal pad to a continuous copper plane on the top layer plus thermal via array to inner ground planes. Per Infineon's OPTIREG linear datasheet, an output capacitor with ESR between 5 milliohm and 500 milliohm is required for stability - X7R 1 microfarat to 10 microfarat ceramics are recommended.
Do not operate the TLS830A4EPV50XUMA1 above its 40 V absolute-maximum input rating - load-dump transients on automotive 12 V buses can briefly exceed 35 V and require external TVS protection. Avoid leaving the EN pin floating - tie it to VIN through a 100 kohm resistor if not actively driven. Finally, verify reverse-battery protection at the system level, because the regulator's internal ESD structures are not rated for continuous reverse input.
Compliance Information
AEC-Q100 Grade 1 qualified per Infineon OPTIREG linear datasheet. RoHS and halogen-free per Infineon product page. Suitable for ISO 7637 and LV124 automotive electrical compliance testing at the system level.
