MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)
ME78M05K3G from MICRONE, in a TO-252-2(DPAK). 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 | Input | power_in | Unregulated input supply; the absolute maximum input voltage is 35 V, and output regulation is specified for VIN 7 V to 20 V, with a 0.33 µF bypass capacitor recommended at the input when the regulator is far from the supply filter. |
| 2 | GND | power_in | Common ground reference; the regulator has no external sense lead, so ground loops and lead resistance drops should be minimized. |
| 3 | Output | power_out | Regulated 5 V output (4.75 V to 5.25 V over IO = 5 mA to 350 mA and VIN = 7 V to 20 V), capable of up to 500 mA maximum output current with adequate heat-sinking. |
