AP7315-28SR-7

Overview

The AP7315-28SR-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.8V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features high ripple rejection of 75dB at 1kHz alongside low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 35µA. It utilizes an SOT23 package (suffix SR) and includes an enable pin for power control.

Feature Summary

Integrates an enable pin to allow active shutdown and power management
Features built-in short circuit protection to clamp output current during faults
Utilizes CMOS process technology for low static current consumption
Includes integrated resistor network for precise fixed output voltage accuracy

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Communication

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and discharge configuration. Confirm that the required output voltage matches the fixed internal setting. Ensure the application load current remains within the 150mA limit. Check for any automotive qualification requirements if operating in harsh environments.

Selection Notes

Select this component when a compact surface-mount solution is required for portable electronics. The SOT23 package offers a small footprint suitable for dense PCB layouts. Consider the enable pin functionality if system power sequencing or standby modes are necessary. Verify input voltage stability to ensure operation within the specified 1.7V to 5.25V range.

Part Context

This part belongs to the AP7315 series of low dropout regulators designed for low-power handheld communication equipment. The series emphasizes high power supply rejection ratio and low noise performance, making it suitable for sensitive analog and RF subsystems. It is available in multiple packages including SOT23, SOT25, and X2-DFN1010-4.
