DIOAP2114H-3.3TRG1

Overview

The AP2114H-3.3TRG1 is a positive voltage regulator IC utilizing CMOS technology to deliver a fixed 3.3V output at up to 1A of current. It features a low quiescent current of 60uA and is designed for stability with various capacitor types, including ceramic, tantalum, and aluminum electrolytic. The device includes integrated safety features such as fold-back short circuit protection and over-temperature shutdown.

Why Choose This Part

This LDO offers a high output current of 1A in a thermal-efficient SOT-223 package, making it suitable for higher power density designs. It remains stable with flexible 4.7uF output capacitors and includes robust ESD protection of 4000V HBM. The fold-back current limit reduces the short-circuit current to 50mA, protecting the internal pass transistor and the upstream power source.

Applications

Getting Started

Ensure a minimum of 4.7uF capacitance is placed close to the input and output pins for stability. Refer to the SOT-223 land pattern guidelines to provide adequate copper area for heat dissipation, as the thermal performance is dependent on the PCB layout. No external programming is required for this fixed-output device.
