78M05-MS

MSKSEMI · Linear Voltage Regulators (LDO) · TO-252

78M05-MS from MSKSEMI, in a TO-252. 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 input supply pin, rated to a maximum input voltage Vi of 35 V and specified for operation with 7 V ≤ Vi ≤ 20 V.
2 GND power_in Common ground reference pin for the regulator, which is connected to the input and output capacitors in the typical application circuit.
3 OUT power_out Regulated 5 V output pin, specified at 4.75 V to 5.25 V over 0 to 125 ℃ with a maximum output current of 0.5 A.
