L7808CV
UMW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220
L7808CV from UMW, 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 | I | power_in | Unregulated input pin; the absolute maximum input voltage is 35 V for VO = 5 to 18 V and 40 V for VO = 24 V. |
| 2 | G | power_in | Ground (common) reference pin for the regulator; the datasheet gives no additional limits for this pin. |
| 3 | O | power_out | Regulated output pin, rated for output current up to 1.2 A, with internal thermal overload and short-circuit protection. |
