AZ2185D-ADJTRG1

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

The AZ2185D-ADJTRG1 is a low dropout positive voltage regulator manufactured by Diodes Incorporated, designed for high-efficiency linear regulation. It delivers an output current of 3A with a maximum dropout voltage of 1.5V at full load. The device features a typical quiescent current of 300µA and includes built-in band-gap reference circuitry, thermal shutdown, and current limit functions. It operates within an input voltage range of 2.75V to 12V and supports an operating junction temperature from -40°C to +125°C. The adjustable version allows output voltage setting via two external resistors.
