LM1117GS-ADJ from HTC Korea TAEJIN Tech, in a SOT-223-3L. 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 | input | Adjustment pin for the ADJ version; the output voltage is set by an external R1/R2 divider and the adjust pin current is specified at 50 µA typ and 120 µA max (VIN - VREF = 1.5V to 12V, IO = 100mA). |
| 2 | VOUT | power_out | Regulated output voltage; the datasheet requires an output capacitor of 10µF or larger for stability and rates the output current at 1A (current limit 1000 mA min/typ at VIN - VREF = 5V). |
| 3 | VIN | power_in | Input supply; operating input voltage is specified up to 12V (15V for the 5.0V fixed version) and the absolute maximum input supply voltage is 20V. |
