TL4050C25IDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL4050C25IDBZR 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, connected to the supply through a series resistor, with the cathode current kept between the minimum IZ,min (41 µA typical, 65 µA max over temperature for the 2.5 V device) and the 15 mA recommended maximum.
2 ANODE passive Anode of the shunt reference, normally tied to ground, and the pin to which pin 3 may be connected.
3 NC/ANODE* passive Pin 3 must be left floating or connected to pin 2 because of a parasitic Schottky diode between pins 2 and 3, and TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise environments.
