Frequently Asked Questions

What input range is documented for IFX54441LDV33XUMA1?

The fetched specifications state a 3.8 V minimum and 20 V maximum input range, which supports operation from several common industrial supply rails.

How much voltage headroom should a designer allow?

Nominal dropout is listed as 0.27 V and maximum dropout as 0.4 V, so worst-case load and temperature conditions should guide headroom.

Which applications benefit from this fixed regulator?

Industrial sensors and controllers needing a fixed 3.3 V rail can use the device when input voltage, load current, thermal limits, and transients are verified.
