AZ1117R-3.3TRE1

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

The AZ1117R-3.3TRE1 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 3.3V output with a maximum current of 1A. It operates within an input voltage range up to 15V and features a typical dropout voltage of 1.15V at full load. The device incorporates a trimmed bandgap reference for high accuracy and includes on-chip thermal shutdown and current limiting protections. Designed for surface mount applications, it utilizes the SOT-89-3 package and supports operation across a junction temperature range from -40°C to +125°C.
