AP7315-31W5-7

Overview

The AP7315-31W5-7 is a low dropout regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.1V with an input voltage range from 1.7V to 5.25V. The device guarantees an output current of 150mA and features high ripple rejection of 75dB at 1kHz. Quiescent current is as low as 35µA, and output noise is 60µVrms from 10Hz to 100kHz. It operates within an ambient temperature range of -40°C to +85°C and utilizes a SOT25 package.

Feature Summary

CMOS-based architecture providing low power consumption and high line/load transient response
Integrated enable pin for turning the regulator on or off
Built-in short circuit protection to clamp output current during faults
High output voltage accuracy with integrated resistor network

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Communication

Procurement Notes

Verify the specific ordering suffix W5 corresponds to the SOT25 package configuration required for your design. Confirm that the non-discharge variant meets system requirements, as discharge versions exist under different part numbers. Ensure compliance with RoHS directives and verify lead-free status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a stable 3.1V rail is needed from inputs between 1.7V and 5.25V. The SOT25 package supports dense PCB layouts. Consider the 35µA quiescent current for battery-powered applications. Verify thermal dissipation capabilities against expected load currents and ambient temperatures to ensure operation remains within the specified -40°C to +85°C range.

Part Context

This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various fixed output voltages ranging from 1.1V to 3.3V. It is available in multiple packages including X2-DFN1010-4, SOT23, and SOT25. The device integrates a voltage reference, error amplifier, and current limit circuit.
