TPS78550QKVURQ1 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 | EN | input | Enable pin: logic high enables the device and logic low disables it; do not float, and connect to IN if unused. |
| 2 | IN | power_in | Input supply pin (1.7 V to 6.0 V operating range) that needs a ceramic capacitor to GND placed as close to the pin as possible. |
| 3 | GND | power_in | Ground pin that must be connected to ground on the board. |
| 4 | OUT | power_out | Regulated output pin requiring 0.47 µF or greater effective capacitance to ground for stability, with 1 µF or larger ceramic recommended for best transient response. |
| 5 | NC | unconnected | No-connect pin not internally connected; connect to ground for best thermal performance or leave floating. |
