AP7315D-18FS4-7B

Overview

The AP7315D-18FS4-7B is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 1.8V with an accuracy of ±1%. It operates within an input voltage range of 1.7V to 5.25V and supports a maximum output current of 150mA. The device features a quiescent current as low as 35µA and includes an integrated enable pin for power control. It incorporates auto-discharge functionality to rapidly reduce the output voltage upon shutdown. Packaged in an X2-DFN1010-4 footprint, it is designed for compact PCB layouts.

Feature Summary

Integrated resistor network provides precise fixed output voltage options.
Built-in discharge circuit ensures rapid output voltage decay when disabled.
CMOS process technology enables low on-resistance and minimal quiescent current consumption.
High ripple rejection capability maintains stable performance under varying load conditions.

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Communication

Procurement Notes

Verify that the FS4 suffix corresponds to the X2-DFN1010-4 package type and confirm the 'D' designation indicates the inclusion of the internal discharge feature. Ensure the ordering suffix matches the required tape and reel packaging quantity specified in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact surface-mount solution with strict space constraints due to its small footprint. Consider the built-in discharge feature if fast output voltage decay is necessary during system sleep modes. Verify that the input voltage range accommodates the specific supply rails available in the target design environment.

Part Context
