DESCRIPTION

The MP2101 is an internally compensated 1.6MHz fixed-frequency PWM step-down switcher with a 200mA low dropout (LDO) linear regulator. It is ideal for portable equipment powered by a single cell Lithium-Ion (Li+) Battery. The MP2101 can provide 800mA and 200mA of load current from a 2.5V to 6V input voltage. Both output voltages can be regulated as low as 0.6V.
