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.
