AZ1084D-2.5TRG1

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

The AZ1084D-2.5TRG1 is a fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 2.5V output at up to 5A load current. It operates with an input voltage range up to 12V 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 a TO-252-2 (3) surface-mount format, it supports an operating junction temperature range from 0°C to +125°C.
