662K
The 662K is an LDO that can be stabilized at 3.3V.
The 662K has a very low static bias current (25uA Typ.) and a maximum input voltage of 6.0V. The 662K is a CMOS buck voltage regulator with high ripple rejection, low power consumption, low voltage difference, overcurrent and short circuit protection. With very low static bias current (25uA Typ.),
The 662K can have an output current of 250 mA with minimal difference between input and output voltages, and still maintain good adjustment rates. Because the voltage difference between input and output is small and the static bias current is small, these devices are particularly suitable for battery-powered products that want to extend the life of useful batteries, such as computers, consumer products and industrial equipment.
