AZ1117CD-1.2TRG1 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 | GND | power_in | Ground reference pin for the fixed 1.2V version (labelled ADJ/GND in the datasheet; it is the adjust pin only on the ADJ version). |
| 2 | OUTPUT | power_out | Regulated 1.2V output (1.176V to 1.224V at 25°C), needs at least a 10µF output capacitor with ESR below 20Ω, current limit 1.35A typical. |
| 3 | INPUT | power_in | Supply input, recommended up to 15V (absolute maximum 18V), with dropout of 1.3V typical at 0.8A for TO252-2. |
