LM3814M-7.0/NOPB Overview


The package includes buck boost converter in version Tube.In this case, voltage regulator has been packaged in the same way as 8-SOIC (0.154, 3.90mm Width).A mounting hole is provided for Surface Mount to mount this current regulator.Temperatures should not exceed -40°C~125°C during operation.Current regulator supports the input voltage of 2V~5.25V.In the case of 8 terminations, which are the practice of terminating a transmission line with a voltage regulator that has the same characteristic impedance as the line itself, they are fairly common.Moreover, current regulator is part of the LM3814 family.This electronic part is mounted in the way of Surface Mount.Providing that it is powered by a 5VV power supply, the constant current should work without any problems.POWER SUPPLY SUPPORT CIRCUIT is the analog IC that this power converter employs.Strong/weak growth of channels: 2.Power Management Circuits, which is a part that contains all of these current regulations, is included in this part.As far as the supply voltage (Vsup) is concerned, it should be greater than 2V.As the maximum supply voltage (Vsup) for its operation reaches 5.25V, it is considered to be operational.
