Product details

The LM4040CIM7-5.0/NOPB: No official successor is listed on the product record.

5 V shunt reference, ±0.5% initial accuracy

The LM4040CIM7-5.0/NOPB is a precision shunt voltage reference from TI's LM4040 family, delivering a fixed 5 V output with ±0.5% tolerance. The shunt architecture means it regulates by sinking current through a cathode resistor — no external bypass capacitor needed, and it can source or sink current as long as the cathode current stays above 80 µA and below 15 mA.

80 µVrms noise, 100 ppm/°C drift

SC-70-5 footprint for tight layouts

Housed in a 5-lead SC-70-5 (SOT-353) package, this reference fits into space-constrained designs — portable instruments, sensor modules, and compact power supplies.

Frequently asked questions

What is the tolerance of LM4040CIM7-5.0/NOPB?

The initial output voltage tolerance is ±0.5% at 25°C. This is a standard precision grade for the LM4040 family, suitable for 8- to 12-bit ADC references and feedback networks where 25 mV of absolute error at 5 V is acceptable.
