DESCRIPTION

The MP2009 is an ultra low noise, low dropout

linear regulator. The output voltage of MP2009

ranges from 1.5V to 4.5V in 100mV increments

and 1% accuracy by operating from a +2.0V to

+6.0V input. It is designed to deliver up to

120mA continuous output current. It achieves a

low 120mV dropout for full load current.

The MP2009 uses an internal PMOS as the

pass element, which consumes 50µA supply

current at no load condition. New innovative

design techniques make MP2009 achieve ultra-

noise bypass capacitor.

The MP2009 are designed and optimized to

work with low value, low cost ceramic

capacitors in space-limiting and performance

consideration. It requires only 1µF (typ) of

output capacitance for stability with any load.

It is available in a 5-pin SC70 package.
