AZ1117S-5.0TRE1

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

The AZ1117S-5.0TRE1 is a positive fixed-output linear regulator from the AZ1117 series, manufactured by Diodes Incorporated. It provides a stable 5.0V output with a maximum current of 1A and operates within an input voltage range up to 15V. The device features a typical dropout voltage of 1.15V at full load and includes on-chip thermal shutdown and trimmed current limiting for protection. It is housed in a TO263 surface-mount package and supports an operating junction temperature range from -40°C to +125°C.
