Overview

The AZ1117CH-5.0TRG1 is a fixed 5V low dropout linear regulator capable of providing up to 1A of output current. It is designed for low-voltage applications requiring efficient thermal management and a stable output across varying load conditions.

Why Choose This Part

This BJT-based LDO offers a high output current of 1A while maintaining low dropout voltage and high thermal stability. It features integrated current limiting and thermal shutdown protection to prevent device failure during fault conditions.

Applications

Single Board Computer Power
Providing a stable 5V rail for logic circuits and peripherals in embedded systems.
Post-Regulation for Switching Supplies
Reducing ripple and noise from high-frequency DC-DC converters for sensitive analog circuitry.
Battery Charger Circuits
Acting as a current-limited voltage source for constant-voltage charging stages in portable devices.
LCD Monitor Power
Regulating internal 5V supply rails for display controllers and interface logic.

Getting Started

Ensure that the input and output capacitors (typically 10uF tantalum or electrolytic) are placed as close as possible to the pins to ensure stability and improve transient response. Consult the datasheet for the recommended PCB copper area to manage heat dissipation from the SOT-223 package under high load.
