Overview
The AP7315D-29FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed output voltage of 2.9V and housed in an X2-DFN1010-4 package. It operates within an input voltage range of 1.7V to 5.25V and guarantees an output current of 150mA. The device incorporates an integrated resistor network for precise voltage regulation with ±1% accuracy at +25°C. Key electrical characteristics include a ripple rejection of 75dB at 1kHz, low output noise of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 35µA. It includes an enable pin and built-in auto-discharge functionality.
Feature Summary
- Integrated enable input allows the regulator to be turned on or off via logic signals.
- Built-in discharge circuit automatically pulls down the output voltage when disabled.
- CMOS process technology ensures high output voltage accuracy and low power consumption.
- Low equivalent series resistance (ESR) requirements facilitate stable operation with small ceramic capacitors.
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify that the specific part number matches the required output voltage and package type before procurement. Confirm compliance with RoHS and Halogen-free standards if environmental regulations apply to your manufacturing process. Ensure the ordering suffix corresponds to the correct tape and reel quantity specified in the manufacturer's documentation.
Selection Notes
Select this component when a compact footprint is required due to its X2-DFN1010-4 packaging. Consider the built-in discharge feature if rapid shutdown response is necessary for the application. Verify that the input voltage range accommodates the system's supply variations while maintaining the desired 2.9V output under load conditions.
Part Context
This device belongs to the AP7315 family of low dropout regulators designed for low power handheld communication equipment. The 'D' suffix indicates the inclusion of an output discharge function, distinguishing it from non-discharge variants. The FS4 code specifies the X2-DFN1010-4 package, which supports dense PCB layouts.

FAQ
What is the function of the EN pin?
The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low puts the device into shutdown mode.
How does the AP7315D differ from the standard AP7315?
The AP7315D variant includes an internal auto-discharge feature that pulls down the output voltage when the device is disabled, whereas the standard version does not.
