... LDOs more difficult because of their unclear specifications and extreme variations over temperature. With the ADP3333 anyCAP LDO, this is no longer true. This device can be used with virtually any good quality capacitor, with no constraint on the minimum ESR. Its innovative design allows the circuit to be stable with just a small 1.0 μ ...
