AZ1117H-1.5TRE1

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

The AZ1117H-1.5TRE1 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 1.5V output at up to 1A load current. It operates with an input voltage range of 3.2V 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. It is housed in a surface-mount SOT-223 package and supports operation across a junction temperature range of -40°C to +125°C.
