Typical Applications
TPS7B7702QPWPRQ1 is suitable for 6 applications: Automotive Active Antenna Power Supply, Infotainment System Power, RF Front-End Power Supply, Battery-Connected Automotive Modules, Telematics and Connectivity Units, Sensor and Actuator Power.
Automotive Active Antenna Power Supply
The TPS7B7702QPWPRQ1 is purpose-built to power low-noise amplifiers in active antenna modules. It accepts 4.5V to 40V input, handles 45V load dump, and delivers two 300mA adjustable outputs, enabling separate supplies for antenna LNAs and other RF front-ends. The current sense feature on each channel lets the ECU remotely monitor antenna health over the coax cable. The HTSSOP-16 package with exposed thermal pad maintains cool operation in tightly enclosed antenna housings. This LDO is AEC-Q100 qualified for automotive reliability.

Infotainment System Power
In automotive infotainment systems, clean analog rails are critical for audio and video processing. The TPS7B7702QPWPRQ1 supplies two 300mA rails with adjustable output from 1.5V to 20V, allowing it to power a variety of ICs from a 12V or 24V battery. Its current sense output helps monitor load current for diagnostics and system protection. With 45V load dump protection, it survives transient overvoltage conditions that occur in automotive electrical systems. The wide input range also supports direct connection to the battery without a pre-regulator.
Recommended
RF Front-End Power Supply
The TPS7B7702QPWPRQ1 is ideal for powering RF front-end modules in automotive communication systems. Its low-dropout architecture provides smooth, low-noise DC power to sensitive RF amplifiers and mixers. The dual outputs allow separate supply rails for transmit and receive paths, minimizing cross-coupling. With 300mA per channel, it can supply both the LNA and active mixer. The integrated current sense provides real-time feedback on load current, enabling adaptive bias control or fault detection. The 4.5V-40V input range makes it compatible with various automotive battery architectures.
Recommended
Battery-Connected Automotive Modules
For modules connected directly to automotive batteries, the TPS7B7702QPWPRQ1 offers a 40V input rating and 45V load dump protection, ensuring safe operation during cranking and transient spikes. It delivers two 300mA rails even when the battery voltage swings from 4.5V to 40V. This makes it suited for headlamps, mirrors, and sensor modules that need a stable 5V or 3.3V rail. The current sense allows the system to detect a shorted load or open circuit through the coax cable, reducing diagnostic time.
Recommended
Telematics and Connectivity Units
Telematics control units require multiple regulated rails for GPS, cellular, and Wi-Fi front-ends. The TPS7B7702QPWPRQ1 provides two adjustable 300mA outputs, enabling power for GNSS LNAs and cellular RF front-ends from a single device. Its wide 4.5V-40V input range accommodates cranking dips and load dump surges. The current sense outputs feed into an ADC, allowing the infotainment head unit to monitor antenna currents and detect faults. Its AEC-Q100 qualification ensures long-term reliability in harsh automotive environments.
Recommended
Sensor and Actuator Power
Automotive sensors and actuators often require clean, current-monitored supply rails. The TPS7B7702QPWPRQ1 delivers up to 300mA per channel with adjustable voltage, making it suitable for powering position sensors, pressure sensors, and small actuators. The integrated current sense provides a low-cost means of detecting short circuits or increased load due to mechanical wear. The HTSSOP-16 package with exposed pad allows reliable operation at high ambient temperatures. Its 40V input voltage range protects against unexpected supply transients.

Key Differentiators
- Dual-channel output with independent current sensing (vs TPS7B7701QPWPRQ1)
- Wide 4.5V-40V input with 45V load dump (vs Standard 36V LDOs)
- AEC-Q100 grade (vs Non-automotive LDOs)
Design Notes
The HTSSOP-16 PowerPAD package requires adequate thermal pad soldering. At 300mA output and high input voltage, power dissipation can exceed 1W per channel. Provide a large copper area on the pad and thermal vias to the bottom layer. According to TI's TPS7B7702EVM, use 2 oz copper for reliable performance.
Place input and output capacitors close to the IC. Use 10uF ceramic input and 10uF ceramic output per channel. Add a small 100nF high-frequency bypass. Keep the current sense traces away from the output to avoid noise coupling.
Do not omit the current sense output filtering; it is a current source, so a resistor to ground is needed. Also ensure the enable pin is pulled high to enable the LDO; floating enable may cause unpredictable startup.
