    I've heard of worries about capacitive loads for emitter followers, For a DC, low power ( <100mA ) load, what should i be looking for? Thanks.

    Welcome to AAC.

    It's confusing when you tack a new question onto an existing thread, so we ask that you always start a new thread for your topic.

    This is the other thread - http://forum.allaboutcircuits.com/showthread.php?t=27111

    Can you say more about the circuit? What is driving the transistor, and the nature of the load? And why the big capacitor?

    sorry bout that,
    This would be to power the control circuitry of a flyback converter, the pic is from the datasheet of the IC i plan to use, not exactly my application, and I just wondered if I'd ever have to worry about stabilitiy problems driving a capacitive load, i just picked a big number of 22uF randomly. Would keeping C11 from the schematic smaller help, and C5 larger be better? Thanks.
