REF3433QDBVRQ1 from Texas Instruments, in a SOT-23-6. 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 | GND_F | power_in | Ground force connection; connect directly to application ground to form Kelvin sensing pair for minimizing IR drops on ground traces. |
| 2 | GND_S | power_in | Ground sense connection; provides feedback of actual ground potential to internal regulator for Kelvin sensing compensation of PCB trace losses. |
| 3 | EN | input | Enable input; apply ≥1.6V for normal operation or ≤0.5V for shutdown mode consuming 3µA maximum. |
| 4 | IN | power_in | Input power supply voltage; supply between VOUT+VDO (50mV minimum dropout at 0mA load) and 12V maximum. |
| 5 | OUT_S | output | Reference output sense connection; part of Kelvin output sensing pair providing feedback to internal regulator for load regulation. |
| 6 | OUT_F | output | Reference output force connection; provides 3.3V nominal output with ±10mA current capability and 72µA to 95µA quiescent current. |
