AP7313-15SAG-7

Overview

The AP7313-15SAG-7 is a fixed-output linear regulator manufactured by Diodes Incorporated, providing a stable 1.5V output with a maximum load current of 150mA. It operates within an input voltage range of 2V to 6V and features a typical quiescent current of 65µA across the full load spectrum. The device incorporates built-in current limit, short circuit, and thermal shutdown protections. It achieves a dropout voltage of approximately 150mV at 150mA and maintains a power supply rejection ratio (PSRR) of 65dB at 100Hz. The component is housed in a SOT-23 package and supports an ambient operating temperature range from -40°C to +85°C.

Feature Summary
