KTP · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92
78L05 TO92 from KTP, in a TO-92. 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 | OUT | power_out | Regulated output of the 5 V regulator, with output voltage specified at 4.8 V min, 5 V typ and 5.2 V max over IO = 1 mA to 40 mA. |
| 2 | GND | power_in | Ground (common) reference pin for the regulator. |
| 3 | IN | power_in | Unregulated input voltage pin; the datasheet gives a maximum input voltage of 20 V and tests the device at VI = 7 V to 20 V. |
