SL7815

Slkor(SLKORMICRO Elec.) · Linear Voltage Regulators (LDO) · TO-220

SL7815 from Slkor(SLKORMICRO Elec.), in a TO-220. 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 INPUT power_in Unregulated input voltage; absolute maximum 35V for VOUT=3.3-18V and 40V for VOUT=20-24V, and for SL7815 the specified input range is 17.5V to 30V at 5mA-1.0A load.
2 GND power_in Ground reference pin for the regulator; quiescent current is 8.0mA maximum at IOUT up to 1.0A.
3 OUTPUT power_out Regulated 15V output (14.40V to 15.60V) for SL7815 delivering up to 1A with short-circuit current typically 250mA.
