AP7365-33WG-7

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

The AP7365-33WG-7 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a stable 3.3V output with a maximum current capacity of 600mA. It operates within an input voltage range of 2V to 6V and features a typical quiescent current of 35µA. The device incorporates a low dropout voltage of 300mV at full load and delivers high power supply rejection ratio (PSRR) of 65dB at 1kHz. Designed for surface-mount applications, it utilizes the SOT-25 package and includes built-in current limit and thermal shutdown protection mechanisms.
