Q
I would like to use an ADR3450 in order to build a 300mA, high precision, 5V
voltage regulator.
How can use it, if the maximun input voltage is really 5.5V (6V in absolute
maximum ratings)?
A
The ADR3450 would need an input voltage of 5.2 to 5.5V. Its output current is
only 10mA. If you want to build a precision regulator that drives 300mA, you
would need much more circuitry. I think you should first consider one of our
regulators like the ADP7102. It has an accuracy of -2% to 1% and can supply
300mA.
