AZ1117ID-2.5TRG1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AZ1117ID-2.5TRG1 is a low dropout linear regulator from the AZ1117I series, manufactured by Diodes Incorporated. It provides a fixed 2.5V output with a maximum continuous current of 1A and features an industrial operating junction temperature range of -40°C to +125°C. The device utilizes a TO252-2 surface-mount package and incorporates a trimmed bandgap reference for ±1% output voltage accuracy. Key electrical characteristics include a typical dropout voltage of 1.3V at 0.8A, a ripple rejection ratio of 70dB at 120Hz, and a maximum quiescent current of 6mA.
