TPS73033DBVR from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input supply voltage, 2.7V to 5.5V range required for stable operation above output voltage plus dropout voltage. |
| 2 | GND | power_in | Regulator ground reference. |
| 3 | EN | input | Enable control input; logic high enables regulator, logic low puts device in shutdown mode; if unused, connect to IN. |
| 4 | NC/NR | unconnected | No-connect pin (new chip) or noise reduction pin (old chip) with external capacitor for filtering internal bandgap reference noise. |
| 5 | OUT | power_out | Regulated output at 3.3V nominal with 200mA maximum continuous output current; typical dropout voltage 120mV at full current. |
