What are the key features of TPS7B7050QPWPRQ1?
- Automotive AEC-Q100 qualified for reliable operation in harsh vehicular environments
- Wide 6 V to 40 V input voltage range with only 0.3 V nominal dropout at 300 mA output
- Integrated power-good flag enables supervised sequencing in multi-rail automotive systems
What is TPS7B7050QPWPRQ1 used for?
The TPS7B7050QPWPRQ1 is designed for automotive body electronics, ADAS sensor modules, and infotainment subsystems requiring stable low-dropout regulation from the vehicle battery rail. Its ultra-low quiescent current makes it ideal for always-on standby circuits such as keyless-entry receivers and telematics modules. The power-good output simplifies supply sequencing in multi-rail ECU designs operating up to 40 V.

Frequently Asked Questions
What output current and dropout voltage does the TPS7B7050QPWPRQ1 deliver?
The TPS7B7050QPWPRQ1 supplies up to 300 mA of output current with a nominal dropout voltage of only 0.3 V, rising to a maximum of 0.4 V at full load. This low dropout characteristic ensures regulation is maintained even when the input rail sags close to the 5 V output, which is critical in automotive battery-powered systems.
How does the TPS7B7050QPWPRQ1 support automotive body-electronics standby circuits?
With an ultra-low quiescent current, the TPS7B7050QPWPRQ1 can power always-on microcontrollers and RF receivers for keyless-entry or telematics over long parking periods from a 12 V vehicle battery. Its 6 V to 40 V input range accommodates load-dump transients up to 40 V, meeting the demands of AEC-Q100 automotive qualification standards.
What is the purpose of the power-good pin on the TPS7B7050QPWPRQ1?
The power-good output on the TPS7B7050QPWPRQ1 is an open-drain flag that asserts when the regulated output reaches approximately 92 % of its nominal voltage. This allows designers to sequence multiple supply rails in ECUs and ADAS modules, preventing processors from booting before their 5 V supply is stable, reducing initialization errors in safety-relevant automotive applications.
Can TPS7B7050QPWPRQ1 replace a non-automotive LDO in a 40 V supply design?
Yes, the TPS7B7050QPWPRQ1 can replace standard 40 V LDOs when AEC-Q100 qualification is required, since it matches common 300 mA / 40 V specifications while adding the power-good feature. The 16-pin HTSSOP (R-PDSO-G16) package is compatible with many existing footprints, and the fixed-output configuration eliminates external resistor tolerances that can affect non-automotive designs.
