LM1117GSF-ADJ from HTC Korea TAEJIN Tech, in a SOT-23-3L. 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 | power_in | For the ADJ part (LM1117GSF-ADJ) this pin is the adjustment input, where the adjust pin current is 50 µA typical and 120 µA maximum at IO = 100mA; on fixed versions it is ground. |
| 2 | VOUT | power_out | Regulated output that delivers up to 300mA, with a dropout voltage of 1.2V maximum at full load and a 1000mA typical current limit, and needs a 10µF or larger output capacitor for stability. |
| 3 | VIN | power_in | Input voltage pin with a maximum DC input of 20V (absolute maximum) and a 12V operating input voltage limit for the ADJ version (15V for the 5.0V version). |
