Product details

3 V shunt reference in SC-70-5 — precision for tight boards

The Texas Instruments LM4040BIM7-3.0/NOPB is a precision shunt voltage reference that delivers a fixed 3 V output with a ±0.2% initial tolerance. The shunt topology means it operates like a precision Zener diode — the 15 mA output current and 67 µA cathode current let you set the bias resistor for the load without a separate supply rail.

Noise floor and drift — the analog designer's concern

For a panel-mount PLC analog input or a battery-monitoring comparator, that drift budget is tight enough to avoid a software calibration routine.

Obsolete — sourcing reality and successor search

Frequently asked questions

What is the replacement for LM4040BIM7-3.0/NOPB?

No official replacement order code is recorded for the LM4040BIM7-3.0/NOPB. For a new design, consider other active members of the LM4040 family in the SC-70-5 package with a 3 V output. The pin-compatible siblings share the same footprint and shunt reference topology; the key difference is the tolerance and temperature coefficient grade you select.

Where can I buy LM4040BIM7-3.0/NOPB?
