Slkor(SLKORMICRO Elec.) · Linear Voltage Regulators (LDO) · TO-220
SL7805 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 SL7805 the electrical specs are given at VIN=10V with 7.5V to 20V regulation range, and absolute maximum is 35V (VOUT 3.3-18V) or 40V (VOUT 20-24V). |
| 2 | GND | power_in | Ground reference for input and output, shared with the common return of the regulator block diagram. |
| 3 | OUTPUT | power_out | Regulated output of 5V (4.80V to 5.20V) for SL7805 at up to 1A output current, with short-circuit current typically 250 mA. |
