LM1117F-5.0 from HTC Korea TAEJIN Tech, in a SOT-89-3. 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 | Adjustment and ground terminal: it is the ADJ pin on adjustable parts and the ground pin on fixed-voltage parts such as the 5.0V version, with an adjustment pin current of 50 to 120 uA typical in the ADJ electrical characteristics. |
| 2 | VOUT | power_out | Regulated output voltage terminal, which delivers 5.0V (4.90 V to 5.10 V over 0 to 1 A and 0 to 125 C junction temperature) with a 1 A output current capability and a 1000 to 1600 mA current limit. |
| 3 | VIN | power_in | Input voltage terminal, with a maximum DC input voltage of 20 V per the absolute maximum ratings and an operating input voltage of 12 V listed in the electrical characteristics. |
