Overview
The AP7167-FNG-7 is a 1.2A adjustable output voltage ultra-low dropout linear regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 2.2V to 5.5V and provides an adjustable output voltage from 0.8V to 5.0V. The device features a typical quiescent current of 125µA and a maximum dropout voltage of 500mV at 1A load. It includes built-in current limit and thermal shutdown circuitry, along with a Power-OK (POK) output for power sequence control. The component is housed in a DFN3030-10 package.
Feature Summary
- Ultra-low dropout performance ensures efficient regulation under varying load conditions
- Integrated Power-OK (POK) open-drain output facilitates precise power sequence management
- Built-in current limiting and thermal shutdown protect the IC during fault conditions
- Stable operation is maintained with any type of output capacitor greater than or equal to 4.7µF
Applications
- Servers and laptops
- Smart phones and PDAs
