LM4040B30IDCKR

Texas Instruments · Voltage Reference · SC-70-5

LM4040B30IDCKR 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 General-purpose pin, normally connected to ground, and the reference for the cathode voltage.
2 * passive Must be left floating or connected to the anode; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise.
3 CATHODE bidirectional Parallel current/voltage input; the cathode current must be kept between the minimum regulation current IZ,min and the 15 mA maximum recommended IZ (absolute maximum continuous cathode current is 25 mA).
4 NC unconnected No internal connection.
5 NC unconnected No internal connection.
