Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
MG78L05T3 from Megain, in a SOT-23-3. 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 | VOUT | power_out | Regulated output voltage pin, nominally 5 V, rated for up to 120 mA when the regulator has adequate heat sinking. |
| 2 | VIN | power_in | Input voltage pin; the recommended input range is 7 V to 30 V, and the absolute maximum rating is -0.3 V to +35 V. |
| 3 | GND | power_in | Ground pin, the common return for the input and output of the regulator. |
