TP1117-1.8Y3 from TECH PUBLIC, in a SOT-223. 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 | Ground reference for the fixed 1.8V output version (adjustment pin on the ADJ version, where output is VOUT=1.25V(1+R2/R1)). |
| 2 | OUTPUT | power_out | Regulated 1.8V output (typ 1.80V) delivering up to 1A maximum output current. |
| 3 | INPUT | power_in | Unregulated supply input with a maximum input voltage of 18V. |
