AZ1117D-3.3TRE1

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

The AZ1117D-3.3TRE1 is a fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 3.3V output at up to 1A load current. It operates within an input voltage range of 4.75V to 15V and maintains a typical dropout voltage of 1.15V at full load. The device features a quiescent current of 5mA and provides ripple rejection of 75dB at 120Hz. Packaged in the TO252-2 (3) surface-mount format, it supports junction temperatures from -40°C to +125°C.
