TPS73733DCQ 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 | Unregulated input supply; the datasheet gives a recommended VIN range of 2.2 V to 5.5 V. |
| 2 | OUT | power_out | Regulator output; requires a 1.0 µF or larger capacitor of any type for stability. |
| 3 | GND | power_in | Ground pin; connect bypass capacitor grounds directly to this pin and tie the ground plane to it. |
| 4 | NR/FB | passive | On the fixed-voltage TPS73733, this is the NR noise-reduction pin, where an external capacitor from NR to ground filters the internal bandgap noise (the datasheet example uses CNR = 10 nF). |
| 5 | EN | input | Active-high enable: above 1.7 V turns the regulator on, below 0.5 V puts it in shutdown, and it must not be left floating. |
| 6 | GND | power_in | Ground, connected to the package tab, which must be tied to ground for heat dissipation. |
