AP7341-285FS4-7

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

The AP7341-285FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.85V with an accuracy of ±1% at +25°C and ±1.5% across the operating temperature range. The device supports a guaranteed continuous output current of 300mA within an input voltage range of 1.7V to 5.25V. Key electrical characteristics include a typical quiescent current of 35µA, a ripple rejection ratio of 75dB at 1kHz, and a low output noise of 60µVrms from 10Hz to 100kHz. Dropout voltage varies based on load and output voltage, reaching a maximum of 0.27V at 300mA for this specific output setting.
