AZ1084D-2.5TRE1

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

The AZ1084D-2.5TRE1 is a discontinued fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 2.5V output at up to 5A load current. It operates within an input voltage range of 4.0V to 7V and features a typical dropout voltage of 1.3V 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 and reel configuration, it supports an operating junction temperature range from 0°C to +125°C.
