LM78M05DCYRG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LM78M05DCYRG from HANSCHIP semiconductor, in a SOT-223. 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 VIN power_in Unregulated input voltage, rated up to 35 V absolute maximum for 5 to 18 V output versions (7 to 20 V specified for LM78M05 at 350 mA).
2 GND power_in Ground reference pin, common to input and output.
3 VOUT power_out Regulated 5 V output (4.9 to 5.1 V at 25 °C) with up to 0.5 A output current, internally current limited.
