ADR433ARZ from Analog Devices, in a SOIC-8. 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 | DNC | unconnected | Do not connect. Do not connect to this pin. |
| 2 | VIN | power_in | Input voltage connection. ADR433 operating supply range is 5.0 V to 18 V. |
| 3 | NIC | unconnected | Not internally connected. This pin is not connected internally. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM | passive | Output voltage trim. Adjusts the output voltage over a ±0.5% range. |
| 6 | VOUT | output | Output voltage. |
| 7 | COMP | passive | Compensation input. Connect a series resistor and capacitor network from COMP to VOUT to reduce overall noise. |
| 8 | DNC | unconnected | Do not connect. Do not connect to this pin. |
