Overview
The TPL8650Q is a series of low-dropout linear regulators with 50-mA maximum output current capability. The TPL8650Q series supports operating voltage range from 4 V to 42 V (−20 V to 45-V maximum operating voltage range).
The TPL8650Q supports an output capacitor range from 1 μF to 50 μF with an ESR range from 0.001 Ω to 5 Ω.
The TPL8650Q integrates full protection with input reverse polarity protection, output short-circuits to ground protection, output short-circuits to battery protection, inductive clamp at the out pin, over-current protection, and over-temperature protection.
With all the above features, the TPL8650Q series is especially suitable for the off-board power supply through a long cable away from the main board in different automotive and industrial systems.
The TPL8650Q series is guaranteed to operate with ambient temperature range from −40°C to +125°C.
