AP7353-28CV4-7

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

The AP7353-28CV4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 2.8V with a maximum guaranteed load current of 250mA. It operates within an input voltage range of 2.0V to 5.5V and features high power supply rejection ratio (PSRR) performance, achieving 90dB at 1kHz and 70dB at 10kHz under specified conditions. The device incorporates an enable pin for power control and utilizes the X1-WLB0707-4 package. Electrical characteristics include a typical quiescent current of 18µA, output noise of 10µVrms from 10Hz to 100kHz, and line regulation of 0.02%/V.
