TLE42962GV50HTSA1 Overview
A linear voltage regulator (also called an LDO when the dropout voltage is small) is a power management integrated circuit that maintains a constant output voltage regardless of input voltage fluctuations and load changes. LDOs sit hierarchically under voltage regulators, which are themselves a category of power management ICs. The TLE4296-2G family specifically addresses the low-current rails required by microcontrollers and sensors in automotive electronic control units, complementing switching DC-DC converters that handle higher-power rails.
Key features include ±4% output voltage accuracy over the full operating range, integrated overtemperature protection, output current limitation, and reverse-polarity protection. The wide input voltage range of 5.5 V to 45 V allows direct connection to the vehicle battery without additional pre-regulation, and the device is qualified to AEC-Q100 standards for automotive reliability.
The TLE42962GV50HTSA1 uses a monolithic bipolar architecture with an on-chip pass transistor and bandgap reference, providing stable regulation across -40 °C to +150 °C junction temperatures. The low quiescent current and integrated protective features make it particularly robust in electrically noisy automotive environments where load-dump and jump-start events are common.
Typical applications include always-on microcontroller power supplies in body and chassis ECUs, sensor power rails, and standby power for infotainment controllers. The compact SCT595-5 package occupies minimal PCB area, enabling dense module designs.
When designing with this regulator, place input and output capacitors close to the IC pins and ensure the dissipation does not exceed package thermal limits at maximum input voltage and load. For higher output current requirements beyond 30 mA, consider the higher-current members of the TLE4296 family or a switching regulator topology.

Typical Applications
TLE42962GV50HTSA1 is suitable for 6 applications: Automotive Body Control Module (BCM) MCU Power, Sensor Power Rail in Chassis ECU, Infotainment Standby Power Supply, Instrument Cluster Always-On Rail, Automotive Lighting ECU Auxiliary Supply, Industrial Sensor Node Power.
Automotive Body Control Module (BCM) MCU Power
The TLE42962GV50HTSA1 is well-suited to supply 5 V microcontroller rails in body control modules, where its 45 V absolute maximum input rating handles 12 V automotive load-dump transients up to 35 V without damage. Its 250 mV dropout maintains regulation during cold-crank events when the bus drops to 6 V, ensuring the MCU never browns out. The AEC-Q100 qualification covers -40 °C to +125 °C ambient operation, and the SCT595-5 footprint minimizes PCB area in densely populated BCMs.
Recommended
Sensor Power Rail in Chassis ECU
In chassis electronic control units, the TLE42962GV50HTSA1 provides a stable 5 V supply for Hall-effect sensors, accelerometers, and pressure sensors that draw under 30 mA. The integrated reverse-polarity and overtemperature protection increases robustness against wiring faults in underbody installations. The low quiescent current and ±4% output accuracy keep sensor readings consistent across the full automotive temperature range, while the small SCT595-5 package supports compact sensor cluster PCBs.
Recommended
Infotainment Standby Power Supply
The TLE42962GV50HTSA1 serves as a standby rail in infotainment head units, supplying 5 V to the always-on microcontroller that handles wake-up and CAN bus monitoring while the main processor is off. Its 45 V input tolerance protects against jump-start events on 24 V truck systems, and the 250 mV dropout ensures the rail stays alive at low battery voltages. The device's reverse-polarity protection prevents damage during battery service, while the SCT595-5 SMD package keeps the standby section physically small.
Recommended
Instrument Cluster Always-On Rail
Digital instrument clusters require an always-on 5 V supply to retain trip computer memory and clock functions even when the ignition is off. The TLE42962GV50HTSA1's low quiescent current minimizes parasitic battery drain, while its 45 V input withstands alternator load-dump transients common in automotive electrical systems. The device operates reliably across -40 °C to +150 °C junction temperatures, ensuring cluster functionality in both cold-start and under-hood heat conditions.
Recommended
Automotive Lighting ECU Auxiliary Supply
LED headlight control modules and adaptive lighting ECUs use the TLE42962GV50HTSA1 to provide a clean 5 V reference rail for microcontroller logic and communication transceivers. The 45 V absolute maximum input withstands jump-start events on commercial 24 V systems, while the integrated current limit and thermal shutdown protect against short-circuit faults on the lighting harness. The PG-SCT595-5 package allows placement close to the MCU for optimal ground bounce performance.
Recommended
Industrial Sensor Node Power
Outside the automotive domain, the TLE42962GV50HTSA1 also fits industrial sensor nodes powered from 24 V bus rails where its 45 V input rating, integrated protection features, and wide temperature range provide robust operation. The fixed 5 V output suits many industrial microcontrollers and 4-20 mA loop transmitters, while the SCT595-5 SMD package supports reflow assembly on mixed-technology boards. Reverse-polarity protection simplifies wiring in field installations where miswiring is a common failure mode.

Key Differentiators

- Compact SCT595-5 footprint with full 5 V/30 mA function (vs TLE4250GHUSA1 (PG-DSO-8))

Design Notes
At VIN = 14 V (typical automotive running voltage), VOUT = 5 V, and IOUT = 30 mA, the TLE42962GV50HTSA1 dissipates approximately (14 - 5) × 0.030 = 0.27 W. The PG-SCT595-5 package's theta_JA is in the range of 80-100 C/W (estimated; consult datasheet for exact value), yielding a junction temperature rise of about 25-30 °C above ambient. Adequate PCB copper pour under the exposed pad (pin 5) is essential to keep Tj below the 150 °C absolute maximum in high-temperature underhood installations.
Place the input capacitor (typically 100 nF to 1 µF ceramic) as close as possible to the IN pin (pin 1) and the output capacitor (typically 1 µF to 10 µF ceramic or low-ESR electrolytic) as close as possible to the OUT pin (pin 3). The exposed thermal pad (pin 5) MUST be soldered to a copper pad of at least the same size on the PCB, connected to ground with multiple thermal vias to the inner/inner-bottom ground plane. Keep high-current switching traces away from the regulator input and output traces to minimize noise injection.
Do not exceed the 45 V absolute maximum input voltage - load-dump transients beyond this will damage the IC. Add an external TVS diode (e.g., 36 V or 40 V SMBJ series) for additional transient suppression. The reverse-polarity protection protects the IC, but high reverse voltage transients can still cause failure. Ensure output capacitor ESR remains within the stable region specified by Infineon; very low-ESR ceramic capacitors may require a small series resistor to prevent instability.
Use a star-ground topology where the regulator ground (pin 2) connects directly to the system ground plane at a single point near the IC, rather than through a long trace. This minimizes ground-loop noise from injecting into sensitive analog sensor signals sharing the same ground. For best EMI performance in automotive environments, route the input and output traces on opposite sides of the IC and avoid parallel runs with switching converter traces. Add a 100 nF X7R bypass capacitor on the input within 3 mm of the IN pin for high-frequency decoupling.
