ME6239A50PG

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

ME6239A50PG from MICRONE, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the LDO. Connect to system ground; on SOT89-3 this pin is also the thermal tab (large center pad) providing heat dissipation for the ~500mW package rating.
2 VIN power_in Regulator input supply. Accepts 5.0V to 30V (for the A50 5.0V option). A 10uF input capacitor (ceramic X5R/X7R for VIN<=15V, electrolytic/tantalum recommended for VIN>15V to suppress >40V spikes) should be placed close to the pin.
3 VOUT power_out Regulated 5.0V output (±1%), 250mA capable with VIN = VOUT + 1.5V. Requires ~10uF output capacitor; short-circuit current typ. 42mA. Dropout typ. 190mV at 50mA / 380mV at 100mA.

CAD (KiCad official)

  • Symbol: ME6239A50PG
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: me6239a50pg-etched.step / me6239a50pg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me6239a50pg.step / me6239a50pg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6239a50pg.step 57 KB You want the bare part, or you mark your own boards.
me6239a50pg-etched.step 1.8 MB You want the part with ME6239A50PG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 462 faces against 42 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
