ME78M05K3G

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.

CAD (KiCad official)

  • Symbol: ME78M05K3G
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)
  • 3D model files: me78m05k3g-etched.step / me78m05k3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me78m05k3g.step / me78m05k3g.glb are the bare package body.
