The Future of Analog IC Technology
MP2009
Ultra-Low-Noise
Low-Dropout, 120mA Linear Regulator
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-
low output voltage noise of 16µV_RMS without a
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.
