STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK
KF80BDT-TR from STMicroelectronics, 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 | Regulator input voltage, operating up to 20 V (absolute maximum -0.5 to 20 V), with a 0.1 µF input capacitor used in the datasheet test circuits. |
| 2 | GND | power_in | Ground, connected internally to the mounting tab (the tab is labelled GND in the DPAK drawing). |
| 3 | OUTPUT | power_out | Regulated 8 V output (7.84 to 8.16 V at 25 °C, 50 mA), up to 500 mA with internal current limit around 1 A, needing a 2.2 to 10 µF output capacitor with ESR 0.1 to 10 Ω. |
