LM4040C41IDCKR

Texas Instruments · Voltage Reference · SC-70-5

LM4040C41IDCKR 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 (ground return) terminal; typically connected to circuit ground, provides return path for regulated current with maximum continuous rating of 25mA per section 6.1.
2 * passive EMI bypass or strap pin; must be left floating or connected to anode; TI recommends connection to anode in high-EMI environments per footnote (1).
3 CATHODE output Cathode terminal providing regulated 4.096V ±0.5% reference output over -40°C to 85°C temperature range with maximum operating current of 15mA.
4 NC unconnected No internal connection within SC-70 5-pin package.
5 NC unconnected No internal connection within SC-70 5-pin package.
