Applications
* that need to vary voltage, such as LCD power supply for PDA. Output will be stable no matter which load capacitors are used but if a low ESR capacitor is used, RSENSE of about 0.1Ω will
be required and phase compensation will be achieved. This makes the use of ceramic capacitors much easier, and a
