Overview
The AP7315D-32FS4-7B is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a 3.2V output with a maximum current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features a typical ripple rejection of 75dB at 1kHz. Output noise is specified at 60µVrms from 10Hz to 100kHz, with quiescent current as low as 35µA. It includes an enable pin and built-in auto-discharge functionality. The component is housed in an X2-DFN1010-4 package.
Feature Summary
- Integrated resistor network delivers fixed output voltages ranging from 1.1V to 3.3V.
- Built-in discharge circuit automatically discharges the output capacitor when disabled.
- CMOS process technology ensures high output voltage accuracy and low power consumption.
- Includes short-circuit protection to clamp output current during fault conditions.
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify the specific ordering suffix FS4-7B corresponds to the X2-DFN1010-4 package and tape & reel packaging quantity of 10000 units. Confirm that the 'D' designation indicates the inclusion of the internal auto-discharge feature for the output node. Ensure compatibility with RoHS 3 standards and halogen-free requirements before finalizing procurement orders.
Selection Notes
Select this variant when a fixed 3.2V rail is required alongside automatic output discharge capabilities. The X2-DFN1010-4 package is suitable for dense PCB layouts requiring minimal footprint. Verify that the 150mA load capability meets system peak current demands while maintaining stability with appropriate ceramic output capacitors.
Part Context
This component belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various output voltages and packages, including SOT23 and SOT25. The AP7315D variant specifically incorporates an N-channel auto-discharge feature, distinguishing it from the standard non-discharge versions within the same family.

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, which actively pulls down the output voltage when the enable pin is low.
How does the enable pin operate?
Driving the EN pin high turns the regulator on, while pulling it low activates shutdown mode and engages the auto-discharge feature.
