LD1117DT18TR from STMicroelectronics, in a DPAK. 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 | Labelled ADJ/GND in the pin diagram; on the fixed 1.8 V LD1117DT18TR this is the ground reference pin (it is the adjustment pin only on the adjustable version). |
| 2 | VOUT | power_out | Regulated output (1.8 V fixed, up to 800 mA output current, needs a 10 µF minimum output capacitor for stability); the TAB is connected to VOUT. |
| 3 | VIN | power_in | Input supply voltage, with absolute maximum DC input of 15 V (18 V when IOUT is lower than 20 mA). |
