LM336MX-5.0 from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection. Leave floating or tie to any convenient node. |
| 2 | V- | passive | Anode (negative) terminal of the shunt reference. Typically connected to ground in a shunt-reference configuration; internally tied to pin 4. Reverse breakdown 4.9-5.1 V at IR = 1 mA. |
| 3 | NC | unconnected | No internal connection. Leave floating or tie to any convenient node. |
| 4 | V- | passive | Anode (negative) terminal of the shunt reference. Internally tied to pin 2; connect both to the same node (typically GND) for lowest inductance. |
| 5 | ADJ | input | Adjust terminal. Allows fine trimming of the 5.0V reference voltage (±1 V typical range per Figure 14) and of the temperature coefficient (per Figure 15) using an external potentiometer. May be left open if adjustment is not needed. |
| 6 | NC | unconnected | No internal connection. Leave floating or tie to any convenient node. |
| 7 | NC | unconnected | No internal connection. Leave floating or tie to any convenient node. |
| 8 | V+ | passive | Cathode (positive) terminal of the shunt reference. In a typical shunt configuration a bias resistor from the supply feeds this pin so that 600 µA to 10 mA flows through the device, developing the 5.00 V reference across V+ to V-. |
