AZ317T-E1

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

The AZ317T-E1 is a three-terminal adjustable positive voltage regulator manufactured by Diodes Incorporated. It provides an output current of up to 1A with a typical dropout voltage of 1.2V at full load. The device utilizes two external resistors to set the output voltage, which can be adjusted down to 1.25V. It features a trimmed bandgap reference ensuring output voltage accuracy within 1%. The component includes built-in current limiting and thermal shutdown protection. It operates within a junction temperature range of 0°C to +125°C and is housed in a TO-220-3 package.
