LM1117GSF-5.0 from HTC Korea TAEJIN Tech, in a SOT-23. 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 | Adjustable/ground pin: the datasheet lists it as ADJ for the adjustable version and GND for the fixed-output versions, so for the fixed 5.0V LM1117GSF-5.0 it serves as the ground return. |
| 2 | VOUT | power_out | Regulated output; for the 5.0V version the output is 5.0V nominal, held within 4.900V to 5.100V over 0 to 300mA and 0 to 125°C junction temperature, and it requires an output capacitor of 10uF or larger for stability. |
| 3 | VIN | power_in | Unregulated input supply: the absolute maximum DC input voltage is 20V, the operating input voltage for the 5.0V version is up to 15V, and the dropout voltage is 1.2V at 300mA full load. |
