Key Features
- Ultra-low 0.4 V maximum dropout voltage enables regulation even with supply voltage close to output, extending battery life
- AEC-Q100 automotive qualification ensures reliable performance from -40°C to +125°C in harsh vehicle environments
- Excellent 0.027% line regulation and 0.12% load regulation provide stable output for noise-sensitive analog and RF circuits
Applications
TPS7133QPWRG4 is designed for automotive ECU power rails, ADAS sensor supply networks, and in-vehicle infotainment systems where AEC-Q100 qualification and stable low-dropout regulation are mandatory. Its ultra-low dropout characteristic makes it ideal for post-battery-regulator stages in start-stop systems where the supply can sag close to the output voltage. Industrial control modules and telecom equipment also use this device to supply precision analog circuits requiring tight line and load regulation.

Frequently Asked Questions
What is the maximum output current and dropout voltage of TPS7133QPWRG4?
The TPS7133QPWRG4 delivers up to 1 A of output current with a maximum dropout voltage of only 0.4 V at full load. This low dropout is achieved through the PMOS pass element, which requires no gate drive above the input rail, making it especially effective in automotive start-stop applications where the 12 V battery can dip to levels close to the regulated output voltage during engine cranking.
Is TPS7133QPWRG4 qualified for automotive use and what temperature range does it cover?
Yes, TPS7133QPWRG4 carries AEC-Q100 Grade 1 qualification and operates over the full automotive temperature range of -40°C to +125°C. The 'Q' in the part number designates automotive qualification, ensuring the device meets stringent reliability and traceability requirements demanded by Tier 1 automotive suppliers following IATF 16949 production standards.
How does the 0.027% line regulation of TPS7133QPWRG4 benefit analog sensor supply designs?
A line regulation of 0.027% means the output voltage shifts by less than 0.27 mV for every 1 V change in input voltage, providing a near-ideal supply for precision ADCs, reference circuits, and analog sensor conditioning stages. This level of stability ensures that even in automotive environments with supply ripple of several volts, sensitive 12-bit and 16-bit ADC measurements remain accurate without additional filtering capacitors.
What package does TPS7133QPWRG4 use and how does it compare to SO-8 alternatives?
TPS7133QPWRG4 uses a 20-pin TSSOP (PDSO-G20) package with a 0.65 mm pitch, measuring approximately 6.5 mm x 4.4 mm. Compared to an 8-pin SO-8 LDO, the extra pins provide dedicated enable, error flag, and sense lines, enabling remote output sensing for load regulation correction and fault notification without consuming additional discrete components, reducing overall BOM complexity in multi-rail automotive boards.
