LM4050AEM3-8.2

Texas Instruments · Voltage Reference · SOT-23-3

LM4050AEM3-8.2 from Texas Instruments, in a SOT-23-3. 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 Cathode output Reference voltage output cathode with operating current range from 60μA minimum to 15mA maximum.
2 Anode power_in Ground return anode terminal, common pin typically connected to ground.
3 NC unconnected No internal connection; parasitic Schottky diode exists between pin 3 and pin 2, so pin 3 must be left floating or connected to pin 2.
