TPS73218DCQR from Texas Instruments, in a SOT-223-6. 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 supply; operating voltage range 1.7 V to 5.5 V |
| 2 | OUT | power_out | Regulated output voltage providing stable regulation without external output capacitor |
| 3 | GND | power_in | Ground connection |
| 4 | NR | passive | Noise reduction pin for connecting external capacitor to bypass bandgap-generated noise and reduce output noise to very low levels; applicable only to fixed voltage versions |
| 5 | EN | input | Enable input; logic high (≥ 1.7 V) enables regulator operation, logic low (≤ 0.5 V) disables regulator with quiescent current ≤ 1 μA |
| 6 | GND | power_in | Ground connection and exposed pad for thermal dissipation |
