AP7315-32SA-7

Overview

The AP7315-32SA-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 3.2V with an accuracy of ±1%. The device supports a guaranteed output current of 150mA and operates within an input voltage range of 1.7V to 5.25V. Key electrical characteristics include a quiescent current as low as 35µA, ripple rejection of 75dB at 1kHz, and output noise of 60µVrms from 10Hz to 100kHz. It features an enable pin for power control and short-circuit protection.

Feature Summary

Integrated enable input allows precise power management and shutdown capabilities
High ripple rejection ratio ensures stable performance against input supply variations
Low output noise design minimizes interference in sensitive signal paths
Built-in short circuit protection safeguards the regulator and load

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Communication

Procurement Notes

Verify the specific ordering suffix SA corresponds to the SOT23 package configuration required for your PCB layout. Confirm that the non-discharge variant meets your system's power-down requirements, as discharge versions carry a different suffix. Ensure compliance with RoHS and halogen-free specifications if mandated by your manufacturing standards.

Selection Notes

Select this component when a fixed 3.2V rail is needed with minimal footprint. The SOT23 package offers a compact solution for dense layouts. Consider the 150mA current limit and 35µA quiescent current for battery-operated applications. Verify input voltage headroom against the dropout voltage curve at maximum load conditions.

Part Context

This part belongs to the AP7315 series of CMOS low dropout regulators. The series is designed for low power handheld communication equipment. Other variants in the family offer different fixed output voltages ranging from 1.1V to 3.3V and are available in X2-DFN1010-4, SOT25, and SOT23 packages.
