What are the key features of TPS7B8633QKVURQ1?

Ultra-low quiescent current for automotive battery-connected designs staying under strict IQ budgets
Wide 4.3 V to 40 V input range tolerates automotive load-dump transients up to 42 V absolute max
AEC-Q100 qualified for use in harsh automotive environments from -40°C to 150°C junction temperature
Integrated power-good flag provides system supervisory feedback without external comparator

What is TPS7B8633QKVURQ1 used for?

TPS7B8633QKVURQ1 is designed for always-on automotive subsystems such as body control modules, telematics units, and gateway ECUs where minimizing quiescent current in sleep mode is critical. Its 40 V input capability makes it suitable for powering 3.3 V microcontrollers and sensors directly from the vehicle battery rail. The TO-252 package eases thermal management on compact automotive PCBs operating across the full -40°C to 150°C temperature range.

Frequently Asked Questions

What input voltage range does TPS7B8633QKVURQ1 support, and can it handle automotive load-dump transients?

TPS7B8633QKVURQ1 accepts an input voltage from 4.3 V to 40 V and withstands an absolute maximum of 42 V, making it resilient to standard automotive load-dump transients. This 40 V rating is well suited for 12 V and 24 V vehicle battery rails.

How does TPS7B8633QKVURQ1 perform in low-power always-on automotive systems with strict quiescent current budgets?

The device is rated ultra-low IQ, minimizing battery drain in sleep or standby modes where the regulator remains powered but the load is off. Combined with a nominal dropout voltage of 0.37 V at 500 mA output current, it maintains regulation efficiently across the automotive operating range of -40°C to 150°C.

Which automotive safety qualification does TPS7B8633QKVURQ1 carry, and what production year was it introduced?

TPS7B8633QKVURQ1 carries AEC-Q100 qualification for automotive applications and was introduced in September 2020. It complies with RoHS and is lead-free, targeting body-control modules, gateways, and sensor-supply rails requiring certified 3.3 V regulation at up to 500 mA.
