AP7375Q-50FDCW-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7375Q-50FDCW-7 is a fixed-output automotive-grade ultra-low-dropout regulator manufactured by Diodes Incorporated. It provides a nominal 5.0V output with a maximum load current of 300mA and operates within an input voltage range of 3V to 45V. The device features a low quiescent current of 2.1µA, high power supply rejection ratio of 85dB at 1kHz, and ±2% output voltage accuracy. It is housed in a U-DFN2020-6 (SWP) package with wettable flanks and supports an operating junction temperature from -40°C to +125°C.
