AP7315-28W5-7

Overview

The AP7315-28W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.8V with a guaranteed maximum 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. It utilizes a CMOS process, includes an enable pin for power control, and incorporates short-circuit protection. The component is housed in a SOT-25 package.

Feature Summary

• Features a dedicated enable pin that allows the regulator to be turned on or off via logic level signals.
• Incorporates built-in short-circuit protection to clamp output current during fault conditions.
• Delivers high ripple rejection performance to minimize noise from the input supply line.

Applications

• RF Supply
• Cameras
• Wireless Adapters

Procurement Notes

Verify the specific suffix W5 corresponds to the SOT-25 package configuration required for your PCB layout. Confirm the 'Blank' discharge designation matches your circuit's shutdown requirements. Ensure the ordering code aligns with the manufacturer's standard tape and reel packaging specifications.

Selection Notes

Select this component when a stable 2.8V rail is needed from a variable input source between 1.7V and 5.25V. The integrated enable feature supports system power management strategies. Verify that the 150mA load requirement does not exceed the thermal dissipation limits of the SOT-25 footprint.

Part Context

This part belongs to the AP7315 series of low dropout regulators designed for low power handheld communication equipment. The series offers various fixed output voltages and packages, including X2-DFN1010-4, SOT23, and SOT25. The AP7315-28W5-7 specifically denotes the 2.8V output version in the SOT-25 package.
