AZ1117D-1.2TRE1

Diodes Incorporated · Linear Voltage Regulators (LDO) · TO-252-2

AZ1117D-1.2TRE1 from Diodes Incorporated, in a TO-252-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ/GND power_in Ground reference pin for the fixed 1.2V version (the adjust pin on the ADJ version).
2 OUTPUT power_out Regulated 1.2V output (2% accuracy), rated for up to 1A with 1.15V dropout at 1A.
3 INPUT power_in Unregulated supply input, with a recommended maximum of 15V (absolute maximum 20V).
