TPS7B8650QKVURQ1 from Texas Instruments, in a TO-252-4. 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 | IN | power_in | Input power voltage pin accepting 3V to 40V with ceramic decoupling capacitor (0.1µF to 1µF recommended, minimum 500nF for EMI performance) placed close to device input. |
| 2 | EN | input | Enable logic input pin with VIL = 0.7V maximum for disabling and VIH = 2V minimum for enabling; must not be left floating due to high input impedance. |
| 3 | GND | power_in | Ground reference pin requiring low-impedance connection to thermal pad for junction-to-ambient thermal resistance of 29.7°C/W in KVU package. |
| 4 | FB/NC | unconnected | No-connect pin in fixed 5V output configuration; can be left floating or tied to GND. |
| 5 | OUT | output | Regulated output voltage pin providing fixed 5V; requires output capacitor (2.2µF to 220µF with ESR 1mΩ to 2Ω) placed close to device for stability. |
