AAT2603 Total Power Solution

The AAT2603 is a highly integrated power management solution for handheld mobile systems. It provides six regulated voltages from a single-cell Lithium-ion/polymer battery or a 5V supply. The six outputs are produced by six regulators; two switching step-down regulators and four low-dropout (LDO) re.
