DIOAP2114HA-3.3TRG1

Overview

The AP2114HA-3.3TRG1 is a 1A CMOS low dropout linear regulator designed to provide a stable 3.3V output from input voltages up to 6V. It features a low quiescent current of 60uA and is housed in a SOT-223 package, making it suitable for applications requiring moderate power in a surface-mount form factor.

Why Choose This Part

This regulator offers fold-back short circuit protection and over-temperature shutdown (OTSD) to ensure robust operation under fault conditions. It is specifically designed to remain stable with various output capacitor types, including 4.7uF ceramic, tantalum, and aluminum electrolytic capacitors.

Applications

Getting Started

To implement this LDO, place a 4.7uF ceramic capacitor close to the input and output pins for stability. Ensure the SOT-223 package has adequate copper pour area on the PCB to manage thermal dissipation when operating near the 1A maximum current limit.
