Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-4
TPS78501QKVURQ1 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: driving it to logic high enables the device and driving it to logic low disables it, so it must not be left floating, and if unused it should be connected to IN. |
| 2 | IN | input | Input pin that should have the nominal recommended value or larger ceramic capacitor from IN to GND, placed as close to the device input as possible (see Recommended Operating Conditions). |
| 3 | GND | power_in | Ground pin that must be connected to ground on the board; the thermal pad is electrically connected to this pin. |
| 4 | OUT | output | Regulated output that requires a 0.47 µF or greater effective capacitance from OUT to ground for stability, with a 1 µF or larger ceramic capacitor recommended for best transient response. |
| 5 | FB | input | Feedback pin that is the input to the control-loop error amplifier and sets the output voltage with external resistors; it must not be floated and is used only on the adjustable-voltage version. |
