Overview
The AP7315-28SA-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.8V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features a quiescent current as low as 35µA. It incorporates high ripple rejection of 75dB at 1kHz and low output noise of 60µVrms from 10Hz to 100kHz. The component utilizes a non-discharge architecture and is housed in a surface-mount SOT-23 package.
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
- Wireless Communication
Procurement Notes
Verify the specific ordering suffix 'SA' corresponds to the SOT-23 package configuration required for your design. Confirm that the non-discharge variant meets system requirements, as discharge versions utilize a different suffix. Ensure compliance with RoHS standards and verify lead-free specifications against project constraints before finalizing procurement.
Selection Notes
Select this component when a fixed 2.8V rail is needed with minimal footprint. The SOT-23 package suits space-constrained layouts. Verify input voltage stability within the 1.7V to 5.25V range. Consider the 150mA current limit for load requirements. Evaluate thermal dissipation needs based on the voltage drop across the regulator under expected load conditions.
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 packages including X2-DFN1010-4, SOT23, and SOT25. The AP7315 family emphasizes low power consumption and fast transient response suitable for battery-operated portable devices.

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 this part include output discharge?
No, the AP7315-28SA-7 uses a non-discharge architecture. A discharge version is available with the 'D' suffix.
