KIA7805AF-RTF
KEC Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK
KIA7805AF-RTF from KEC Semicon, in a DPAK. 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; the absolute maximum input voltage is 35 V for KIA7805/7815 and 40 V for KIA7818/7824 (Ta=25°C), and input-to-ground surges above the rating may destroy the device. |
| 2 | GND | power_in | Ground reference terminal; the package serves as GND, and a negative voltage must not be applied to the input or output terminals. |
| 3 | OUTPUT | power_out | Regulated output voltage (5 V to 24 V depending on the variant); the output must not be driven above the input voltage, and a protection diode is recommended when it can be. |
