Overview
The AP7315-295FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed output voltage of 2.95V 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 provides high output voltage accuracy of ±1%, ripple rejection of 75dB at 1kHz, and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is as low as 35µA, with an operating ambient temperature range of -40°C to +85°C.
Feature Summary
- Includes an enable input for power control and integrated resistor network for fixed output voltage delivery.
- Built on a CMOS process providing low R DS(ON), high PSRR, and low output noise characteristics.
- Features short circuit protection that clamps the output current to approximately 60mA during faults.
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
Procurement Notes
Verify the specific ordering suffix FS4-7B confirms the X2-DFN1010-4 package and tape & reel packaging quantity of 10000 units. Ensure the part number matches the exact 2.95V output requirement and confirm compliance with RoHS standards before procurement.
Selection Notes
Select this component when a precise 2.95V output is required alongside minimal footprint constraints due to the X2-DFN1010-4 package. Consider its low quiescent current and high ripple rejection for battery-powered or noise-sensitive portable applications requiring stable regulation under varying load conditions.
Part Context
This component belongs to the AP7315 series of low dropout regulators designed for low power handheld communication equipment. The series offers various fixed output voltages ranging from 1.1V to 3.3V across multiple package options including SOT23, SOT25, and X2-DFN1010-4.

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 it into shutdown mode. It must not be left floating.
How does the AP7315 handle short circuits?
When the VOUT pin is shorted to GND, short circuit protection triggers and clamps the output current to approximately 60mA to protect the regulator from overheating.
