# LM4030AMF-4.096

**Texas Instruments** · Voltage Reference · SOT-23-5

LM4030AMF-4.096 from Texas Instruments, in a SOT-23-5. 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 | N/C | unconnected | No-connect pin; leave floating. |
| 2 | GND, N/C | power_in | Listed as ground or no connect; the datasheet does not say which applies, so tie to ground or leave unconnected per the application. |
| 3 | N/C | unconnected | No-connect pin; leave floating. |
| 4 | VREF | power_in | Reference voltage output; for the 4.096 V option the reverse breakdown voltage is 4.096 V at ISHUNT = 130 µA, with minimum operating current 130 µA. |
| 5 | GND | power_in | Ground connection. |
