AZ1117D-ADJTRE1 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 | ADJ/GND | input | Adjust pin on the adjustable AZ1117D-ADJ, where R1 and R2 set VOUT = VREF*(1+R2/R1)+IADJ*R2 with VREF 1.25V typ and IADJ 60µA typ; it is the ground reference on fixed-voltage versions. |
| 2 | OUTPUT | power_out | Regulated output delivering up to 1A with a typical dropout of 1.15V at 1A, current limit 1.25A min, and the adjustable version giving 1.25V to 12V. |
| 3 | INPUT | power_in | Unregulated input supply, recommended up to 15V (absolute maximum 20V), and it must be at least about 1.25V above VOUT at 1A. |
