What are the key features of TPS7A5401QRGRRQ1?
- AEC-Q100 Grade 1 automotive qualification ensures reliable operation from -40 °C to +150 °C in harsh vehicle environments
- 4 A output current with only 150 mV typical dropout voltage for high-efficiency power management on low-headroom rails
- ±0.5% output voltage accuracy over temperature supports precision ADC reference and DSP core voltage rails
- Ultra-low noise output of 6.7 µVrms (100 Hz to 100 kHz) for sensitive RF, audio, and sensor supply applications
- Wide input voltage range of 1.1 V to 6.5 V accommodates diverse automotive and industrial power supply architectures
What is TPS7A5401QRGRRQ1 used for?
The TPS7A5401QRGRRQ1 is designed for automotive ADAS, infotainment, and body control module power rails where AEC-Q100 Grade 1 qualification, 4 A current capability, and ±0.5% voltage accuracy are mandatory. Its low 6.7 µVrms output noise makes it equally valuable in radar sensor analog supply chains and camera module power trees that require clean rails from 1.1 V to 6.5 V input. Industrial instrumentation and medical imaging equipment also leverage its wide temperature range of -40 °C to +150 °C and tight regulation for precision analog circuitry.

Frequently Asked Questions
What output current and dropout voltage does the TPS7A5401QRGRRQ1 provide for automotive power rails?
The TPS7A5401QRGRRQ1 delivers up to 4 A of output current with a typical dropout voltage of 150 mV and a maximum of 645 mV at full load. This low dropout characteristic is critical for automotive 3.3 V rails powered from a 3.6 V post-regulator, where headroom is tight and efficiency must be preserved over the -40 °C to +150 °C operating range.
How does the output noise specification of the TPS7A5401QRGRRQ1 benefit radar and RF sensor designs?
The TPS7A5401QRGRRQ1 achieves 6.7 µVrms output noise from 100 Hz to 100 kHz, which directly lowers the noise floor of sensitive RF front ends, 77 GHz radar transceivers, and precision ADCs supplied from this LDO. Competitive LDOs with 20–50 µVrms noise can degrade SNR and dynamic range in these applications, making the ultra-low noise specification a key differentiator.
Is the TPS7A5401QRGRRQ1 suitable for ADAS camera module power trees requiring tight voltage accuracy?
Yes, the TPS7A5401QRGRRQ1 is well suited for ADAS camera module supplies because its ±0.5% output voltage accuracy over temperature ensures stable 1.8 V or 1.2 V core voltages for image signal processors. Its AEC-Q100 Grade 1 rating and 4 A capacity support multi-camera platforms with up to 12 W of imaging loads operating at input voltages from 1.1 V to 6.5 V.
How does the TPS7A5401QRGRRQ1 compare to the TPS7A53 series for higher-voltage automotive applications?
The TPS7A5401QRGRRQ1 is optimized for input voltages up to 6.5 V while the TPS7A53 family supports inputs up to 36 V, so for 12 V automotive battery-connected rails the TPS7A53 is the correct choice. However, for post-DC-DC LDO filtering scenarios where the input rail is already regulated below 6.5 V, the TPS7A5401QRGRRQ1's lower dropout of 150 mV and 6.7 µVrms noise make it a superior post-regulator choice.
