MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

78M08-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 input Input voltage pin; the absolute maximum input voltage is 25 V, and output regulation is specified for 10.5 V ≤ Vi ≤ 23 V.
2 GND power_in Ground reference pin; the datasheet gives no electrical limits for this pin.
3 OUT power_out Regulated 8 V output pin (typical output voltage 8 V), rated for a maximum output current IOM of 0.5 A.
