**MCC Micro Commercial Components** · Linear Voltage Regulators (LDO) · SOT-89

MC78L05FA-TP from MCC Micro Commercial Components, 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 | OUT | power_out | Regulated 5 V output; the maximum output current is 0.1 A (IO), with internal short-circuit current limiting and internal thermal overload protection. |
| 2 | GND | power_in | Ground (common) reference pin for the regulator. |
| 3 | IN | power_in | Unregulated input supply to the regulator; the maximum input voltage is 30 V per the maximum ratings table. |
