The low dropout regulator is a valuable tool in the power-supply roster; don’t assume its "drawbacks" should automatically rule it out of your design.
Precision resistor arrays stabilize and enable miniaturization of electronic circuits
Design How-To 6/24/2010 Post a comment
This article shows how thin-film chip resistor arrays can positively affect a circuit’s electric stability while at the same time minimizing the area required. Using the example of a voltage divider, the relative parameters “tolerance matching” and “TCR tracking” are explained and the temperature behavior of resistor arrays is discussed. In addition, it is shown how the tolerance and temperature coefficient of resistors can be controlled during the production proces
