ROHM Semiconductor CMOS LDO Regulators for Portable Devices

Power management has become an increasingly important design consideration for numerous products, especially those relying on battery power. Complicating the power management situation, as more features get integrated into products, the number of required voltage supplies increases. With a common 3.6-V lithium-ion battery, a highly integrated product such as a smart phone can require ten or more different voltages.
