LM1117GSF-3.3 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 | GND / ADJ | power_in | Ground pin for the fixed 3.3V version (the datasheet's ADJ function applies to the adjustable variant only), and the datasheet gives no other limit for this pin. |
| 2 | VOUT | power_out | Regulated 3.3V output, specified at 3.234V to 3.366V over 0 to 300mA and 0 to 125°C junction temperature, and it requires an output capacitor of 10µF or larger for stability. |
| 3 | VIN | power_in | Input supply pin, with an operating input voltage of 12V for the 3.3V version and a 20V absolute maximum DC input voltage, and the dropout is 1.2V at 300mA. |
