AP7315-18W5-7

Overview

The AP7315-18W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 1.8V 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. It utilizes a CMOS process, offering low quiescent current as low as 35µA and low output noise of 60µVrms from 10Hz to 100kHz. The component includes an enable pin for power control and short-circuit protection. It is housed in a SOT-25 package.

Feature Summary

Integrated enable pin allows for precise power management and shutdown control
High ripple rejection capability ensures stable performance against input noise
Low output noise design suitable for sensitive RF and communication circuits
Built-in short circuit protection safeguards the regulator under fault conditions

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Adapters

Procurement Notes

Verify the specific ordering suffix W5 corresponds to the SOT-25 package configuration required for your PCB layout. Confirm that the non-discharge variant matches your system's power-down requirements. Ensure compatibility with RoHS compliance standards if operating in regulated regions. Cross-reference the datasheet revision to confirm electrical characteristics align with your design specifications before finalizing procurement.

Selection Notes

Select this component when a fixed 1.8V rail is needed with minimal footprint using the SOT-25 package. It is appropriate for applications requiring low quiescent current and high PSRR. Consider the 150mA output limit and ensure thermal dissipation fits within the 400mW power rating. Verify that the input voltage remains within the 1.7V to 5.25V operational window for optimal line regulation.

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 ranging from 1.1V to 3.3V. It is available in multiple packages including X2-DFN1010-4, SOT23, and SOT25. The device is based on a CMOS process and integrates a voltage reference, error amplifier, and current limit circuit.
