Overview
The AP7315D-23W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.3V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features a typical ripple rejection ratio of 75dB at 1kHz. Quiescent current is specified as low as 35µA, and the output noise is 60µVrms from 10Hz to 100kHz. It utilizes an SOT25 package and includes an integrated enable pin.
Feature Summary
- Integrated N-channel auto-discharge circuit for rapid output voltage decay when disabled
- High power supply ripple rejection capability for sensitive analog applications
- Low output noise performance suitable for RF and communication circuits
- Built-in enable control pin for system power management
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 standards and Halogen-free requirements before procurement. Ensure the ordering quantity aligns with standard tape and reel packaging specifications provided in the manufacturer documentation.
Selection Notes
Select this component for designs requiring a fixed 2.3V rail with high PSRR and low quiescent current. The D suffix indicates the inclusion of an internal auto-discharge feature, which is critical for applications needing fast shutdown times. Verify that the load current does not exceed the 150mA limit under all operating conditions.
Part Context
This component belongs to the AP7315 series of CMOS low dropout regulators. The series offers various fixed output voltages ranging from 1.1V to 3.3V. The 'D' designation specifically denotes the version equipped with an output discharge resistor, distinguishing it from the non-discharge variant.

FAQ
What is the function of the 'D' suffix in the AP7315D-23W5-7?
The 'D' suffix indicates that the regulator includes an internal auto-discharge circuit connected to the output, allowing the output voltage to decay rapidly when the enable pin is pulled low.
How does the enable pin operate on this device?
The regulator is turned on by driving the EN pin high and enters shutdown mode when the EN pin is pulled low. The pin must not be left floating during operation.
