TPAP7343D-33FS4 from TECH PUBLIC, in a DFN1x1-4. 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 | VOUT | power_out | Regulated output voltage pin (3.3V fixed for the -33 option, up to 300mA output current). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input, active high, must not be left floating. |
| 4 | VIN | power_in | Input supply, 1.4V to 5.5V recommended operating range (absolute maximum -0.3V to 6.5V to GND). |
| 5 | GND | power_in | Center exposed pad labeled GND on the pin configuration drawing and not listed in the pin table. |
