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. |
