AP7315-22FS4-7B

Overview

The AP7315-22FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed output voltage of 2.2V. It operates within an input voltage range of 1.7V to 5.25V and guarantees an output current of 150mA. The device provides high output voltage accuracy with a tolerance of ±1% and achieves a ripple rejection of 75dB at 1kHz. Output noise is specified at 60µVrms from 10Hz to 100kHz, while quiescent current is as low as 35µA. It utilizes an X2-DFN1010-4 package.

Feature Summary

CMOS-based architecture providing high output voltage accuracy and low on-resistance
Integrated enable pin for power control and internal resistor network for fixed output voltages
Low output noise and high power supply ripple rejection suitable for sensitive applications
Compact footprint design enabling dense PCB layout

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Communication

Procurement Notes

Verify the specific ordering suffix FS4-7B corresponds to the X2-DFN1010-4 package and tape & reel packaging configuration. Confirm that the component meets RoHS compliance standards and halogen-free requirements. Ensure the selected part number matches the required 2.2V fixed output specification before procurement.

Selection Notes

Select this component when a stable 2.2V rail is required with minimal board space constraints. The X2-DFN1010-4 package offers the smallest footprint in the series. Consider the 150mA current limit and 1.7V minimum input voltage for battery-powered designs. Verify thermal dissipation capabilities based on the expected load current and ambient temperature conditions.

Part Context

This part belongs to the AP7315 family of low dropout regulators designed for low power handheld communication equipment. The series supports various fixed output voltages ranging from 1.1V to 3.3V. It is built using a CMOS process to ensure low quiescent current and efficient operation across a wide input voltage range.
