Overview
The AP7315-295SR-7 is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed output voltage of 2.95V and packaged in SOT23 (SR). 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 with a tolerance of ±1% at room temperature. Key electrical characteristics include a ripple rejection ratio of 75dB at 1kHz and a low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is specified as low as 35µA.
Feature Summary
- Integrated enable pin for power control
- High ripple rejection capability
- Low output noise performance
- Built-in short circuit protection
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos

Procurement Notes
Verify the specific ordering suffix SR confirms the SOT23 package type and tape & reel packaging format. Confirm that the 295 designation corresponds to the required 2.95V fixed output voltage. Ensure compliance with RoHS and lead-free requirements if applicable to your manufacturing standards. Check for any automotive qualification requirements if the application demands AEC-Q100 certification.
Selection Notes
Select this component when a precise 2.95V rail is needed for sensitive analog or RF circuits. The low noise and high PSRR make it suitable for powering stages where signal integrity is critical. Consider the SOT23 package for standard surface mount assembly processes requiring a compact footprint. Evaluate thermal dissipation needs based on the expected load current and ambient operating conditions.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series utilizes a CMOS process to achieve low quiescent current and high efficiency. The AP7315 family offers various fixed output voltages and packages, including X2-DFN1010-4, SOT23, and SOT25, allowing designers to optimize PCB space and layout density.

FAQ
Does the AP7315-295SR-7 feature an internal discharge resistor?
No, the AP7315 variant without the 'D' suffix does not include an internal auto-discharge resistor. To ensure the output discharges when disabled, an external resistor should be connected across the output and ground.
What is the recommended capacitor configuration for stability?
The datasheet recommends using ceramic capacitors with low ESR. A minimum input capacitor of 0.47μF is suggested between VIN and GND, and an output capacitor is required to improve transient response and maintain stability.
