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

AZ1117ID-1.2TRG1 from Diodes Incorporated, in a TO-252. 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-output versions (including the -1.2V variant) the ADJ/GND pin is internally tied to the on-die divider tap and acts as the device ground return. Connect directly to the system ground plane.
2 OUTPUT power_out Regulated 1.2V DC output (typ 1.2V, 1.176-1.224V at TJ=25°C). Drives up to 1A continuous with ~1.3V dropout at 0.8A (typ). Requires a minimum 10µF output capacitor with ESR < 20Ω for stability. This terminal is also electrically connected to the exposed heat-slug tab of the TO252-2 package.
3 INPUT power_in Unregulated input supply. Recommended operating range up to 15V (18V absolute maximum). Must exceed VOUT by at least the dropout voltage (typ 1.3V @ 0.8A for TO252-2). A 10µF (or larger) input capacitor is recommended.
