The Future of Analog IC Technology
Low-Dropout, 120mA Linear Regulator
The MP2009 is an ultra low noise, low dropout
linear regulator. The o utput voltage of MP2009
ranges from 1.5V to 4.5 V in 100mV increments
and 1% a ccuracy 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 MP200 9 uses an internal PMOS as the
pass eleme nt, which consumes 50µA supply
current at no load co ndition. New innovative
design techniques make MP2009 achieve ultra-
low output voltage noise of 16µV RMS without a
noise bypass capacitor.
The MP200 9 are desig ned and optimized to
work with low value, low cost ceramic
capacitors in space- limiting and p erformance
consideration. It requ ires only 1µ F (typ) of
output capacitance for stability with any load.
It is available in a 5-pin SC70 package.
