Reference voltage source using operational amplifier

Published:2011/4/14 4:38:00 Author:may | Keyword: Reference voltage source, operational amplifier | From:SeekIC

The features of this circuit: 1 operational amplifier will not cause drift, voltage regulator tube have thecharacteristic of temperature compensation 2 the output voltage of pin 3 is very low, so, output current must higher than 10mA, it has no influence to voltage regulator performance and drift characteristic 3 choosing appropriately among R1、R2 and R4 can make the output voltage has a wider range (U3>U2) .
