Frequently Asked Questions
What is the output voltage accuracy of the LM4050QAIM3X5.0/NOPB?
The LM4050QAIM3X5.0/NOPB provides a nominal 5.0V output with a tight tolerance range of 4.97V to 5.03V, representing approximately 0.6% accuracy. This precision makes it suitable for high-accuracy ADC reference, precision measurement circuits, and calibration applications.
How does a shunt voltage reference like the LM4050QAIM3X5.0/NOPB differ from a series reference?
A shunt voltage reference like the LM4050QAIM3X5.0/NOPB operates in parallel with the load and requires a series resistor to set the operating current, similar to a Zener diode. Unlike series references, the shunt reference draws current even at no load, but offers simpler two-terminal connections and works well in low-noise, low-power applications.
Is the LM4050QAIM3X5.0/NOPB suitable for automotive applications?
Yes, the LM4050QAIM3X5.0/NOPB carries an automotive Q1 qualification (QAIM), indicating it has been tested and certified for use in automotive-grade designs. It is appropriate for under-hood sensors, body control modules, and infotainment systems where reliability over a wide temperature range is required.
What package does the LM4050QAIM3X5.0/NOPB come in?
The LM4050QAIM3X5.0/NOPB is available in a SOT-23-3 surface-mount package with just three pins, offering an extremely compact footprint suitable for space-constrained PCB designs. It is supplied in tape-and-reel format compatible with automated SMT assembly equipment.
