Product details

Shunt topology — no separate supply, but watch the resistor

The external series resistor sets the bias current. The part needs at least 73 µA through the cathode to regulate, and the maximum cathode current is 15 mA.

Lifecycle and sourcing posture

The LM4050QCIM3-4.1/NOPB carries an Active product status with ROHS3 compliance.

Frequently asked questions

Is LM4050QCIM3-4.1/NOPB AEC-Q100 qualified?

Yes, the LM4050QCIM3-4.1/NOPB is part of TI's Automotive, AEC-Q100 series, qualified for automotive-grade applications.

How does LM4050QCIM3-4.1/NOPB compare to LM4040?

The LM4050QCIM3-4.1/NOPB is the AEC-Q100 automotive-qualified variant of the standard LM4040. The commercial LM4040 lacks the automotive temperature range and qualification, so this part is the correct choice for under-hood or chassis-domain designs that require AEC-Q100.
