    There are several circuits that use op amps and BJT or MOS pass devices to create current sources with high output impedance. Take a look at the following reference designs: TIPD101 , TIPD102 , TIPD107 and also the XTR110 and XTR111 integrated circuits…

    Sainer, I suspect your stability issues are more related to the feedback loop of the switching regulator as opposed to the op amp itself. In general, capacitive load or capacitance on the inverting feedback node causes stability issues. Also, the output…
