AZ1117R-1.8TRE1

Diodes Incorporated · Linear Voltage Regulators (LDO) · SOT-89-3

AZ1117R-1.8TRE1 from Diodes Incorporated, in a SOT-89-3. 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 GND power_in Ground reference for the fixed 1.8V AZ1117R-1.8 (this pin is ADJ on the adjustable version).
2 OUTPUT power_out Regulated 1.8V output (1% accuracy, up to 1A, current limit 1.25A min) which is also connected to the package tab (VOUT).
3 INPUT power_in Unregulated supply input, recommended up to 15V (absolute maximum 20V) with dropout of 1.15V at 1A.
