AP7353-30CV4-7

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

The AP7353-30CV4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 3.0V with a guaranteed maximum output current of 250mA. It operates within an input voltage range of 2.0V to 5.5V and features a typical quiescent current of 18µA. The device incorporates high power supply rejection ratio (PSRR) performance, achieving 90dB at 1kHz and 70dB at 10kHz under specified load conditions. Output noise is maintained at 10µVrms across the 10Hz to 100kHz bandwidth. The unit utilizes X1-WLB0707-4 packaging and includes integrated thermal shutdown and short-circuit protection mechanisms.
