Overview
The AP7315D-29W5-7 is a low dropout regulator manufactured by Diodes Incorporated, featuring an integrated resistor network for fixed output voltage. It operates within an input voltage range of 1.7V to 5.25V and guarantees an output current of 150mA. The device provides a fixed output voltage of 2.9V with an accuracy of ±1%. 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 utilizes a CMOS process and includes an enable pin.
Feature Summary
- Includes an internal discharge circuit that activates when the enable pin is pulled low, ensuring rapid output voltage decay in shutdown mode.
- Features high power supply ripple rejection and low output noise, maintaining stable performance under varying load conditions.
- Incorporates an enable input pin that allows precise control over the regulator's active and shutdown states.
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify the specific ordering suffix W5 corresponds to the SOT25 package configuration required for your design. Confirm the D suffix indicates the inclusion of the auto-discharge feature on the output pin. Ensure compatibility with RoHS compliance standards and check for any automotive qualification requirements if deploying in regulated environments.
Selection Notes
Select this component when a fixed 2.9V output is required alongside strict low-noise specifications. The SOT25 package offers a compact footprint suitable for dense PCB layouts. Consider the built-in discharge function if system power-down speed is critical. Verify that the input voltage remains within the specified 1.7V to 5.25V range during all operating conditions.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for low-power handheld communication equipment. The series supports various fixed output voltages ranging from 1.1V to 3.3V. It is available in multiple packages including X2-DFN1010-4, SOT23, and SOT25 to accommodate different space constraints.

FAQ
What is the function of the 'D' suffix in the part number?
The 'D' suffix indicates that the regulator includes an internal auto-discharge circuit connected to the output pin, which pulls the output voltage down when the device is disabled.
How does the enable pin operate?
Driving the EN pin high enables the regulator, while pulling it low puts the device into shutdown mode. The pin must not be left floating to ensure proper operation.
