AZ1084D-5.0TRE1

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

The AZ1084D-5.0TRE1 is a discontinued fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 5.0V output at up to 5A load current. It operates within an input voltage range of up to 12V and features a maximum dropout voltage of 1.5V at full load. The device incorporates on-chip thermal limiting and current limiting circuits for protection against overload conditions. Packaged in the TO-252-2 (3) surface-mount format with a Tape & Reel configuration, it supports an operating junction temperature range from 0°C to +125°C.
