AZ1084T-3.3E1

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

The AZ1084T-3.3E1 is a fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a stable 3.3V 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 under full load conditions. The device incorporates on-chip thermal limiting and current limiting circuits for robust protection against overload and excessive junction temperatures. Designed for surface-mount applications, it utilizes the TO-220-3 package and supports operation across a temperature range from 0°C to +125°C.
