KEC Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
KIA78L05F-RTF from KEC Semicon, in a SOT-89-3. 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 | OUTPUT | power_out | Regulated 5V output (4.8V min, 5.0V typ, 5.2V max at Tj=25°C) with up to 150mA maximum output current; use a 0.1µF output capacitor and do not apply more than 10V above the output voltage to this pin. |
| 2 | GND | power_in | Ground and case connection (SOT-89 tab) for the regulator, with the package rated at 500mW power dissipation. |
| 3 | INPUT | power_in | Unregulated input voltage, absolute maximum 35V for KIA78L05, with a 0.33µF input capacitor used in the test circuit. |
