Overview
The AP7311-28WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 2.8V output with a maximum load current of 150mA. The device operates within an input voltage range of 2V to 6V and features a typical quiescent current of 65µA at full load. It utilizes an SOT-25 package and includes built-in protections such as current limit, short circuit protection, and thermal shutdown. The regulator ensures stability with low ESR ceramic capacitors.
Feature Summary
- Integrated enable pin for power management control
- Fast transient response capability for dynamic loads
- Built-in thermal shutdown and current limiting safeguards
Applications
- Battery powered devices
- Portable devices
- Notebook and desktop computers and peripherals
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS compliance standards required for your manufacturing process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.8V rail is required with minimal ground current consumption. The wide input voltage range supports direct battery operation. Verify that the application load does not exceed 150mA and that the PCB layout accommodates the SOT-25 footprint. Consider the thermal resistance characteristics if operating near maximum ambient temperature limits.
Part Context
This regulator belongs to the AP7311 series, designed for low-power portable electronics. It distinguishes itself through fast start-up times and excellent line/load regulation. The series offers both adjustable and fixed output options, catering to diverse voltage requirements in compact mobile and computing applications.

FAQ
What is the minimum capacitance required for stable operation?
A 1µF ceramic capacitor is recommended on both the input and output pins to ensure stability and proper transient response.
How does the device handle over-current conditions?
The AP7311-28WG-7 includes current limit protection that clamps the output current to approximately 300mA during overload, and short-circuit protection that reduces it to 50mA if the output is grounded.
