TL4050B25IDCKR

Texas Instruments · Voltage Reference · SC-70-5

TL4050B25IDCKR from Texas Instruments, in a SC-70-5. 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 ANODE power_in Anode (low-side return); connect to GND rail; in high-EMI applications TI recommends connecting the NC pin to this pin.
2 NC unconnected No internal connection; middle pin on left side of SC-70-5 body; leave unconnected or connect to Anode per high-EMI guidance.
3 CATHODE power_out Cathode; regulated 2.5 V shunt reference output; operating cathode current IZ = 60 μA (typ) to 15 mA (max); dynamic impedance ZZ = 0.3 Ω typ at IZ = 1 mA, 120 Hz.
4 NC unconnected No internal connection; bottom pin on right side of SC-70-5 body.
5 NC unconnected No internal connection; top pin on right side of SC-70-5 body; TI recommends connecting to Anode in high-EMI applications.
