LM4041A12IDBZR from Texas Instruments, in a SOT-23. 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 | Cathode | output | Reference voltage output of 1.225V nominal with tolerance ±1.2mV at 25°C accepting 45μA to 12mA shunt current with temperature coefficient ±100ppm/°C full range. |
| 2 | Anode | power_in | Ground/negative reference pin normally grounded providing the return path for cathode current. |
| 3 | NC | unconnected | No connect pin which must float or be connected to pin 2 (anode) to suppress electromagnetic interference if needed. |
