AZ1086S-3.3TRE1

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

The AZ1086S-3.3TRE1 is a low dropout positive voltage regulator manufactured by Diodes Incorporated, designed for applications requiring stable power delivery with minimal heat generation. This specific model provides a fixed output voltage of 3.3V and supports a maximum load current of 1.5A. It features a typical dropout voltage of 1.3V at full load, ensuring efficient operation even when the input voltage is close to the output level. The device integrates essential protection mechanisms, including thermal shutdown and current limiting, to safeguard against overload conditions. It operates within a junction temperature range of 0°C to 125°C and utilizes a TO-263-3 (D2PAK) surface-mount package for reliable PCB integration.
