AZ1117ID-ADJTRG1 from Diodes Incorporated, in a TO-252. 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 | Adjust pin of the ADJ version, which sources about 60 µA typical (120 µA max) into the reference divider; it serves as GND on the fixed-output versions. |
| 2 | OUTPUT | power_out | Regulated output; a minimum 10 µF output capacitor is required, with ESR below 20 Ω. |
| 3 | INPUT | power_in | Unregulated input supply; recommended maximum VIN is 15 V, with an absolute maximum of 18 V, and VIN must exceed VOUT by at least 1.5 V for regulation. |
