Overview
The AP7315-25SR-7 is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 2.5V output voltage and housed in an SOT23 package with the SR suffix indicating non-discharge functionality. It operates within an input voltage range of 1.7V to 5.25V and guarantees a maximum output current of 150mA. The device provides high output voltage accuracy of ±1% at room temperature and achieves a ripple rejection of 75dB at 1kHz. Its quiescent current is as low as 35µA, and it exhibits low output noise of 60µVrms from 10Hz to 100kHz.
Feature Summary
- Includes an integrated enable pin for power control and shutdown mode management
- Features built-in short circuit protection that clamps output current during faults
- Utilizes CMOS process technology for low on-resistance and low quiescent current operation
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm the exact package type, output voltage tolerance, and discharge configuration. Ensure compatibility with required PCB footprint dimensions and thermal dissipation requirements before finalizing procurement orders.
Selection Notes
Select this component when a stable 2.5V rail is required for low-power portable electronics. Consider the SOT23 package size constraints and verify that the 150mA current capability meets the load demands. Evaluate the need for the enable pin functionality versus tying it permanently high based on system power management strategies.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various fixed output voltages and packaging options including X2-DFN1010-4, SOT23, and SOT25. It is characterized by high PSRR and low noise, making it suitable for noise-sensitive subsystems in mobile devices.
Replacement Considerations
AP7315-25SA-7 (Same output voltage, SA package variant)
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 the device into shutdown mode.
How does the SR suffix differ from SA?
Both are SOT23 packages, but the SR suffix indicates a non-discharge version, whereas other variants may include an auto-discharge feature.
