Low drop out linear regulator stability

    Has anyone used a resistor in the output circuit of an LDO to ensure the
    required ESR needed for stability?

    Some (most?) LDO linear regulators have to be used with output capacitors
    that have an ESR in a specific range in order to ensure stability (eg you
    can't just slap any old 100nF ceramic cap on the output). So what do you do
    if you have high frequency IC that need to be decoupled?
