Slkor(SLKORMICRO Elec.) · Linear Voltage Regulators (LDO) · TO-220
SL7812 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; for the SL7812 the datasheet specifies 14.5V to 30V line-regulation range, with absolute maximum of 35V (VOUT up to 18V). |
| 2 | GND | power_in | Ground reference pin common to input and output, per the block diagram. |
| 3 | OUTPUT | power_out | Regulated 12V output (11.52V to 12.48V) delivering up to 1A, with short-circuit current of 250mA typical at VIN=35V. |
