L7905ACV

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

L7905ACV from STMicroelectronics, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT power_out Regulated negative output voltage pin, capable of delivering output current up to 1.5 A with a heat sink.
2 INPUT power_in Unregulated DC input voltage pin; per Table 2, max input is -35 V for VO = -5 to -18 V variants (applies to the -5 V L7905AC).
3 GROUND power_in Common ground/reference pin for the regulator.
