AP7315-25W5-7

Overview

The AP7315-25W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.5V with an accuracy of ±1%. The device supports a maximum output current of 150mA and operates within an input voltage range of 1.7V to 5.25V. Key electrical characteristics include a typical ripple rejection of 75dB at 1kHz, an output noise voltage of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 35µA. It features fold-back short circuit protection and is housed in a SOT25 package.

Procurement Notes

Verify the specific part number against official Diodes Incorporated documentation to confirm the exact output voltage, package type, and discharge configuration. Ensure that the ordering suffix matches the required packaging format and that the component meets all necessary environmental compliance standards for the intended application.

Selection Notes

Select this component when a stable 2.5V supply is required for low-power portable electronics. Consider the 150mA current limit and the specific dropout voltage characteristics relative to the minimum input voltage. Evaluate the need for the enable function and ensure the PCB layout accommodates the thermal requirements of the SOT25 package.

Part Context

This component belongs to the AP7315 series of high PSRR low noise LDOs. It utilizes a CMOS process and includes an integrated resistor network for fixed output voltages ranging from 1.1V to 3.3V. The series is designed for applications requiring small footprint and dense PCB layout, available in X2-DFN1010-4, SOT23, and SOT25 packages.
