MS78L15

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

MS78L15 from MSKSEMI, in a SOT-89. 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 VO power_out Regulated 15V output (14.4V to 15.6V at Tj=25°C), with maximum output current of 100 mA and a 0.1µF output capacitor shown in the application circuit.
2 GND power_in Ground reference pin, shared by the input capacitor (0.33µF) and output capacitor (0.1µF) returns in the application circuit.
3 VI power_in Unregulated input voltage, absolute maximum 35V for the 10V-15V rated versions, with a 0.33µF input capacitor shown in the application circuit.
