TL4050A50QDBZRQ1

Texas Instruments · Voltage Reference · SOT-23-3

TL4050A50QDBZRQ1 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 passive Cathode of the two-terminal shunt reference, fed from the supply through series resistor RS, with IZ limited to a 15 mA recommended maximum (20 mA absolute maximum) and no output capacitor required.
2 ANODE power_in Anode (reference return) of the shunt reference; a parasitic Schottky diode is connected between pins 2 and 3.
3 NC/ANODE passive 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 environments and floating it where there is no significant switching noise.
