AZ1086D-3.3E1

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

The AZ1086D-3.3E1 is a fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a stable 3.3V output at up to 1.5A load current. It operates within an input voltage range of 1.5V to 15V and features a typical dropout voltage of 1.3V at full load. The device integrates thermal shutdown and current limiting protection circuits for enhanced reliability. It is housed in a TO-263 (D2PAK) surface-mount package with three pins, suitable for applications requiring efficient power management in compact designs.
