AZ1117R-ADJTRE1

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

The AZ1117R-ADJTRE1 is a positive adjustable low dropout linear regulator manufactured by Diodes Incorporated. It delivers an output current of up to 1A with a maximum dropout voltage of 1.25V at full load. The device operates within an input voltage range of 3.2V to 15V and provides an adjustable output voltage from 1.25V to 13.75V using two external resistors. It features a quiescent current of 10mA, ripple rejection of 75dB at 120Hz, and thermal shutdown protection. The component is housed in a SOT-89-3 surface-mount package and supports junction temperatures from -40°C to +125°C.
