Texas Instruments · Voltage Reference · SC-70-5
TL4050A50IDCKR 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 | passive | Anode (reference return) of the two-terminal shunt reference, connected to the low side of the circuit. |
| 2 | * | passive | Marked with an asterisk; a parasitic Schottky diode exists between this pin and the anode pin, so it should be left floating or connected to the anode (pin 1), and TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise applications. |
| 3 | CATHODE | passive | Cathode of the shunt reference, which carries the regulated 5 V output (VZ) and operates at cathode current IZ up to 15 mA. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
