Overview
The AP7315D-285W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.85V with an accuracy of ±1%. The device supports a guaranteed continuous 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 ratio of 75dB at 1kHz, a maximum quiescent current of 60µA, and an output noise voltage of 60µVrms from 10Hz to 100kHz. It features an enable pin for power control and includes short-circuit protection.
Feature Summary
- Integrated enable pin allows precise on/off control of the regulator output
- Built-in auto-discharge circuit ensures rapid output voltage decay when disabled
- CMOS process technology enables low quiescent current consumption
- High ripple rejection ratio minimizes power supply noise impact
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify that the specific part number suffix matches the required package type and discharge configuration. Confirm compliance with RoHS and Halogen-free standards if environmental regulations apply. Ensure the ordering quantity aligns with the standard tape and reel packaging specifications provided by the manufacturer.
Selection Notes
Select this component for applications requiring a stable 2.85V rail with minimal footprint. The SOT25 package offers a compact solution for dense PCB layouts. Consider the internal discharge feature for systems requiring fast shutdown times. Verify that the load current requirements do not exceed the 150mA guarantee across the full operating temperature range.
Part Context
This device belongs to the AP7315 series of low dropout regulators designed for low power handheld communication equipment. The 'D' suffix indicates the inclusion of an output discharge resistor, while 'W5' specifies the SOT25 surface-mount package. The series is characterized by high PSRR and low output noise suitable for sensitive RF circuits.

FAQ
What is the function of the EN pin?
The EN pin controls the operation of the regulator. Driving it high enables the output, while pulling it low shuts down the device.
How does the D suffix affect the device behavior?
The D suffix indicates that the regulator includes an internal auto-discharge resistor, which rapidly pulls the output voltage to ground when the device is disabled.
