AZ1117CD-1.8TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

AZ1117CD-1.8TRG1 from Diodes Incorporated, in a TO-252-2. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the regulator. On fixed-voltage versions (1.8V here) the internal adjust resistors tie this pin to the internal reference divider, so it functions as GND. Also connected to the tab.
2 OUTPUT power_out Regulated 1.8V output (typ), min 1.764V / max 1.836V over temperature. Requires a minimum 10µF output capacitor with ESR < 20Ω for stability. Current limit typ 1.35A.
3 INPUT power_in Unregulated input supply, absolute max 18V, recommended max 15V. Must be at least VOUT + VDROP (≈1.3V at 0.8A) above the target output. A 10µF input decoupling capacitor is recommended.
