Applications
TPS7A6133QKVURQ1 is designed for automotive ECU power rails, ADAS sensor supply circuits, and in-vehicle infotainment systems where a 40 V-tolerant LDO is required to regulate down from the 12 V or 24 V vehicle battery. Its AEC-Q100 qualification and wide temperature range make it suitable for under-hood and body-electronics modules that must survive harsh thermal cycling between -40°C and 125°C.

Frequently Asked Questions
How does TPS7A6133QKVURQ1's 40 V input rating protect automotive circuits during load-dump transients?
Automotive 12 V batteries can produce load-dump transients exceeding 35 V for several hundred milliseconds. TPS7A6133QKVURQ1's 40 V maximum input (45 V absolute maximum) provides margin above these transients without requiring an external clamping diode, simplifying the protection network and reducing BOM in ECU power supply stages that must survive ISO 16750-2 load-dump profiles.
What is the power dissipation of TPS7A6133QKVURQ1 when regulating from 14 V to 3.3 V at 300 mA?
At 14 V input and 3.3 V output with 300 mA load, the dropout across the LDO is 10.7 V, giving a power dissipation of 3.21 W (10.7 V × 300 mA). This requires careful thermal management; with the 4-pin WSON package soldered to a copper thermal pad, the device can sustain this dissipation with a junction-to-board thermal resistance of roughly 40°C/W at 25°C ambient, keeping the junction below 150°C.
Is TPS7A6133QKVURQ1 qualified for safety-critical automotive applications requiring AEC-Q100?
Yes. TPS7A6133QKVURQ1 carries AEC-Q100 automotive qualification, meeting Grade 1 stress test requirements for operation from -40°C to 125°C ambient. This qualification covers HTOL, HAST, temperature cycling, ESD immunity above 2 kV HBM, and latch-up robustness, making it acceptable for ADAS, body control modules, and powertrain ECUs subject to PPAP and TS 16949 supply chain requirements.
How does the 0.3 V typical dropout of TPS7A6133QKVURQ1 benefit low-margin power designs in vehicles?
With only 0.3 V typical dropout, TPS7A6133QKVURQ1 can regulate a 3.3 V output from an input as low as 3.6 V, preserving regulation even during battery brown-down conditions where vehicle voltage sags to 6 V to 9 V during cold cranking. Compared to standard LDOs with 1 V to 2 V dropout, this low-dropout design extends the usable input range by at least 0.7 V, keeping downstream logic alive longer during engine start events.
