DESCRIPTION
The MP2030 is a very low dropout, dual supply
linear regulator. The use of two supplies allows
the BIAS to control an NMOS device. The
NMOS device supplies power to the load via
the IN. In this way the input supply can be just
above the desired output, yet still provide very
good regulation performance due to the higher
bias supply. The BIAS operates from a 2.5V to
5.5V input and regulates the output voltage to
as low as 0.9V, and as high as 3.8V.
The MP2030 can supply up to 3A of load
current with a typical dropout voltage of 150mV.
The BIAS runs the internal reference and drive
circuitry, while the output current comes directly
from the IN for high efficiency regulation.
The low bias current of 220uA makes the
MP2030 ideal for use in battery-powered
applications. The BIAS can be directly applied
from the battery while IN is powered from the
high efficiency buck regulator. This will reduce
the output noise and decoupling capacitor.
Other features of MP2030 include thermal
overload and current limit protection, power
good indicator, stability with ultra low ESR
ceramic capacitors as low as 1uF, and fast
transient response. The MP2030 is available in
10-pin QFN (3mm x 3mm), and in QFN (5mm x
5mm) packages.
