TL4050C50QDBZRQ1

Texas Instruments · Voltage Reference · SOT-23

TL4050C50QDBZRQ1 from Texas Instruments, in a SOT-23. 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 passive Cathode terminal of the shunt reference; the absolute maximum continuous cathode current is -10 mA to 20 mA and the recommended cathode current is 15 mA maximum.
2 ANODE passive Anode terminal of the shunt reference; in the SOT-23-3 package a parasitic Schottky diode sits between pins 2 and 3, so pin 3 must be floating or connected to this pin.
3 NC unconnected Must be left floating or connected to pin 2 (anode); TI recommends tying it to the anode in high-EMI or high-frequency switching-noise applications and leaving it floating otherwise.
