AP7353-30FS4-7

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

The AP7353-30FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 3.0V with an accuracy of ±1%. It supports a guaranteed output current of 250mA and operates within an input voltage range of 2.0V to 5.5V. The device features a typical quiescent current of 18µA and standby current as low as 0.1µA. Ripple rejection measures 90dB at 1kHz and 70dB at 10kHz under specified load conditions. Output noise is limited to 10µVrms from 10Hz to 100kHz. The component utilizes the X2-DFN1010-4 package and functions reliably across an ambient temperature range of -40°C to +85°C.
