AP2318AMP-ADJTRE1

Overview

The AP2318AMP-ADJTRE1 is an adjustable ultra-low dropout (ULDO) linear regulator from Diodes Incorporated, housed in a PSOP-8 package. It supports an input voltage range of 2.5V to 12V and delivers up to 1A output current with ±1.5% accuracy. Key electrical parameters include a typical dropout voltage of 0.5V at 1A, quiescent current of 250µA, and thermal shutdown at +150°C. The device features an enable pin, ESD protection rated at 3000V (HBM), and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Adjustable output voltage configuration utilizing external resistors
• Integrated on-chip thermal shutdown for overload protection
• High electrostatic discharge robustness with Human Body Model rating of 3000V

Applications

• Notebook computers
• USB devices
• Add-on cards
