ADR3433ARJZ-R7 from Analog Devices, 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 FORCE | power_in | Ground drive connection that carries the ground return current, and is used together with GND SENSE in the four-wire Kelvin connection. |
| 2 | GND SENSE | power_in | Ground voltage sense connection that must be connected directly to the lowest potential point in the application, drawing negligible current. |
| 3 | ENABLE | input | Enable connection: pulling it to 0.7 V or below puts the device in low-power shutdown, 0.85 × VIN or above enables it, and levels between 0.7 V and 0.85 × VIN should be avoided. |
| 4 | VIN | power_in | Input voltage connection, specified for 3.5 V to 5.5 V on the ADR3433 with a 6 V absolute maximum supply and a minimum input slew rate of 0.1 V/ms. |
| 5 | VOUT SENSE | input | Reference output sense connection that must be connected directly to the voltage input of the load device to maintain maximum output accuracy. |
| 6 | VOUT FORCE | power_out | Reference voltage output that sources up to 10 mA and sinks up to 3 mA, with the output capacitor mounted as close to this pin as possible. |
