LM1117IDTX-ADJ from Texas Instruments, 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 | output | Adjustment pin establishing 1.25V reference voltage between output and ADJ pin for programming output voltage from 1.25V to 13.8V using external resistor divider network. |
| 2 | VOUT | power_out | Regulated output voltage pin supplying up to 800mA continuous output current; requires minimum 10µF tantalum output capacitor for stability. |
| 3 | VIN | power_in | Unregulated input voltage pin requiring 1.4V minimum differential above output voltage, maximum 20V absolute rating to ground. |
