LM78L05MK from HGSEMI, in a SOT-89. 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 | VOUT | power_out | Regulated 5 V output (4.8 to 5.2 V at TJ = 25°C), delivering up to 100 mA output current. |
| 2 | GND | power_in | Ground reference pin for input and output, which is also connected to the package tab shown in the connection diagram. |
| 3 | VIN | power_in | Unregulated DC input with a maximum rating of 30 V for the 5 V version (VO = 3.3 to 10 V) and a recommended 7 to 20 V for regulation. |
