TPS71401DCKT from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Feedback input for the adjustable output. Connect the mid-point of an external resistor divider from OUT to GND here to program VOUT from 1.205 V to 8.8 V. Internal reference is 1.2 V (typ); feedback bias current is ~2 nA. |
| 2 | GND | power_in | Device ground return. All voltages are referenced to this pin. |
| 3 | NC | unconnected | No connect. Not connected internally; tie to ground for best thermal performance or leave floating. |
| 4 | IN | power_in | Input supply pin, 2.5 V to 10 V operating range (30 V absolute max on the new chip). Bypass to GND with a 0.1 µF or larger capacitor (0.047 µF or larger for the legacy chip). |
| 5 | OUT | power_out | Regulated output, up to 80 mA. Requires a 1 µF or larger capacitor to GND for stability on the new chip (≥0.47 µF for the legacy chip). Dropout is ~415 mV at 50 mA / ~650 mV at 80 mA. |
