Texas Instruments · Voltage Reference · SOT-23-5
LM4120IM5-4.1 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 | REF | unconnected | REF pin which must be left unconnected; sensitive to noise and capacitive loading. |
| 2 | GND | power_in | Negative supply or ground connection. |
| 3 | Enable | input | Analog enable input pulled to VIN for normal operation; forcing to ground turns off device output. |
| 4 | VIN | power_in | Positive supply input; operates from 2 V to 12 V. |
| 5 | VOUT | output | Reference voltage output; sources up to 5 mA or sinks up to 5 mA. |
