Combination Voltage And Current Regulator Circuit


Posted on May 9, 2012

This voltage-regulator/cuiTent-liimter combination can be made from two 7805 regulators as shown. Rl, R2, and R3 shouldbe selected for a 5-V drop at the maximum allowable currant limit. SI selects one of the three current values. Do not forget that Ul requires 5 mA to operate and this means that the minimum current limit setting should be 10 mA or more (Rl - 1.25 kQ).
