# KIA7824AF-RTF

**KEC Semicon** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

KIA7824AF-RTF from KEC Semicon, in a TO-252-2(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 to the regulator; the maximum ratings table lists an input voltage of 40 V for the KIA7818AF/KIA7824AF. |
| 2 | COMMON | power_in | Common (GND) reference terminal; a negative voltage must not be applied to the input or output terminals relative to it. |
| 3 | OUTPUT | power_out | Regulated 24 V output (VOUT 23.0 to 25.0 V at IOUT = 100 mA, Tj = 25 °C), with output current in excess of 1 A. |
