78M05AS

YFW · Linear Voltage Regulators (LDO) · TO-263

78M05AS from YFW, in a TO-263. 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 IN power_in Unregulated positive input voltage, absolute maximum 25 V and specified over 7 to 25 V in the electrical characteristics.
2 GND power_in Ground reference for input and output, also connected to the metal tab of the TO-263 package.
3 OUT power_out Regulated fixed 5 V output (4.75 to 5.25 V) delivering up to 1.0 A with thermal overload and short circuit protection.
