Overview
The AP7315-285SA-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.85V with an accuracy of ±1%. The device supports a maximum output current of 150mA and operates within an input voltage range of 1.7V to 5.25V. It features a quiescent current as low as 35µA, ripple rejection of 75dB at 1kHz, and output noise of 60µVrms from 10Hz to 100kHz. The component utilizes an SOT23 package and includes an enable pin for power control.
Feature Summary
- Integrates an enable input to switch the regulator on or off
- Includes internal current limit circuitry for protection
- Utilizes CMOS process technology for low power consumption
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify that the ordering suffix SA corresponds to the SOT23 package configuration. Confirm the specific output voltage code matches the required 2.85V specification. Ensure compliance with RoHS directives if environmental standards are mandatory for the project. Check datasheet notes regarding lead-free and halogen-free definitions before finalizing procurement.
Selection Notes
Select this component when a fixed 2.85V rail is needed with minimal footprint in portable designs. The integrated enable pin allows for system-level power management. Verify that the input voltage remains within the 1.7V to 5.25V operating range. Consider the 150mA current limit when sizing the load requirements for the application.
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 ranging from 1.1V to 3.3V. It is available in multiple packages including X2-DFN1010-4, SOT23, and SOT25 to accommodate different PCB layout densities.

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.
Does the AP7315-285SA-7 include short circuit protection?
Yes, the device includes a current limit circuit that triggers during a short circuit condition to clamp the output current and protect the regulator.
