TPS73633DRBR from Texas Instruments, in a VSON-8-EP(3x3). 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 | OUT | output | Regulator output voltage at nominal 3.3V; achieves stability without external output capacitor. |
| 2 | N/C | unconnected | No connection; leave unconnected. |
| 3 | NR | passive | Noise reduction bypass pin for fixed voltage version only; connect external capacitor from this pin to ground to filter internal bandgap-generated reference noise and reduce output noise. |
| 4 | GND | power_in | Ground reference; includes exposed thermal pad for heat dissipation; connection to ground plane recommended for optimal thermal performance. |
| 5 | EN | input | Digital enable control input; logic high (≥1.7V) enables regulator output regulation, logic low (≤0.5V) disables to shutdown mode with quiescent current <1μA; TTL/CMOS compatible. |
| 6 | N/C | unconnected | No connection; leave unconnected. |
| 7 | N/C | unconnected | No connection; leave unconnected. |
| 8 | IN | power_in | Input power supply connection; operating voltage range 1.7V to 5.5V; minimum input voltage required is greater of VOUT + VDO (75mV typical at 400mA load) or 1.7V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
