Overview
The AP7313-20SAG-7 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 2.0V output with a maximum continuous load current of 150mA. It operates within an input voltage range of 2V to 6V and features a typical dropout voltage of 150mV at full load. The device incorporates low quiescent current technology, drawing approximately 65µA across the entire operating temperature range of -40°C to 85°C. Integrated protection mechanisms include thermal shutdown, short-circuit protection, and current limiting to ensure reliability under fault conditions.
Feature Summary
- Ultra-fast start-up time enables rapid power delivery without compromising low ground current consumption.
- Excellent transient response capability maintains stable voltage supply during rapid load transitions.
- Built-in thermal shutdown and current limit functions protect the integrated circuit against overheating and overcurrent events.
Applications
- Battery powered devices
- Portable Devices
- Notebook and Desktop Computers and Peripherals
Procurement Notes
Verify that the component matches the specific 2.0V fixed output designation and SOT-23 package configuration. Confirm compliance with RoHS directives and lead-free finish requirements as specified in the manufacturer documentation. Ensure the ordering suffix corresponds to tape and reel packaging for automated assembly processes.
Selection Notes
Select this regulator when a precise 2.0V rail is required for low-power portable electronics. The wide input voltage tolerance accommodates single-cell battery systems. Evaluate thermal dissipation capabilities based on the expected ambient temperature and PCB copper area to ensure operation remains within safe junction temperature limits.
Part Context
This component belongs to the AP7313 series of low dropout linear regulators manufactured by Diodes Incorporated. The series offers multiple fixed output voltage options ranging from 1.0V to 3.3V. All variants share common electrical characteristics, including high PSRR and fast transient response, while differing primarily in their regulated output voltage levels and corresponding marking codes.
Replacement Considerations

FAQ
What is the minimum capacitance required for stable operation?
A 1µF ceramic capacitor is recommended for both the input and output pins to ensure stability and proper transient response.
How does the device handle short-circuit conditions?
Short-circuit protection triggers when the output voltage drops below 200mV, clamping the output current to approximately 50mA to prevent damage.
