... These ESR limitations make designing with LDOs more difficult because of their unclear specifications and extreme variations over temperature. With the ADP3338 anyCAP LDO, this is no longer true. It can be used with virtually any good quality capacitor, with no constraint on the minimum ESR. This innovative design provides circuit stability with just a small 1 µ ...

... ADP3338 is mounted affects thermal performance. When mounted to the minimal pads of 2 oz. copper, as shown in Figure 22 (a), θ is 126.6°C/W. Adding a small copper pad JA under the ADP3338, as shown in Figure 22 (b), reduces the θ 102.9°C/W. Increasing the copper pad to one square inch, as shown in Figure 22 (c), reduces the θ Figure 22 ...
