AP7315-33SR-7

Overview

The AP7315-33SR-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a stable 3.3V output with a maximum current of 150mA. It operates within an input voltage range of 1.7V to 5.25V and features high power supply rejection ratio (PSRR) of 75dB at 1kHz. The device incorporates an enable pin for power control and utilizes a CMOS process for low quiescent current consumption of 35µA. Packaged in the SOT23-3 form factor, it supports an operating temperature range from -40°C to +85°C.

Feature Summary

Integrated enable pin allows precise power management and shutdown control
High ripple rejection capability ensures clean power delivery for sensitive circuits
Low output noise characteristic suitable for RF and communication applications
Built-in short circuit protection safeguards against overcurrent conditions

Applications

Smart Phone/PAD
RF Supply
Cameras
Portable Videos
Wireless Adapters

Procurement Notes

Verify that the ordering suffix SR corresponds specifically to the SOT23 package variant when sourcing components. Confirm the absence of the 'D' suffix to ensure the non-discharge version is procured, as this affects output behavior during shutdown. Cross-reference the datasheet revision DS38352 Rev. 2 - 2 to ensure alignment with current manufacturing specifications and marking information.

Selection Notes

Select this component for designs requiring a compact footprint and low standby current. Ensure input voltage remains within the specified 1.7V to 5.25V range to maintain regulation. Verify that the load does not exceed the 150mA guaranteed output current limit. Consider the thermal dissipation capabilities of the SOT23 package under maximum load conditions to prevent overheating.

Part Context

This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various fixed output voltages and packaging options including X2-DFN1010-4, SOT25, and SOT23. The specific model integrates standard LDO features with added enable functionality for enhanced system power management.
