Overview
The AP7311-20WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 2.0V 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 ambient operating temperature range extends from -40°C to +85°C.
Feature Summary
- Integrated enable pin for power management control
- Fast transient response suitable for dynamic load applications
- Stable operation with low ESR ceramic capacitors
- Built-in over-current and thermal protection mechanisms
Applications
- Battery powered devices
- Portable electronic equipment
- Notebook and desktop computer peripherals
- CD-ROM, DVD, and LAN cards
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. Confirm that the SOT-25 footprint matches your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.0V rail is required with minimal ground current consumption. The wide input voltage range accommodates single-cell battery systems. Verify that the application load does not exceed 150mA continuous current. Ensure adequate thermal dissipation on the PCB to maintain junction temperatures within safe limits during high-load operations.
Part Context
This part belongs to the AP7311 series of low dropout regulators designed for portable electronics. The series offers various fixed output voltages ranging from 1.0V to 3.3V, alongside adjustable versions. All variants share common features including fast start-up times and stability with small ceramic output capacitors, making them versatile solutions for space-constrained designs.
Replacement Considerations
Compatible substitutes include other AP7311 variants with different fixed output voltages (e.g., AP7311-18WG-7 for 1.8V or AP7311-25WG-7 for 2.5V) if voltage requirements change. Adjustable versions like AP7311-ADJWG-7 can replace fixed outputs using external resistors. Cross-reference pinouts and thermal characteristics carefully.
