MAS9162 is a low dropout voltage regulator with an
enable/disable pin, which allows device to be turned
off or on by pulling control to low or high.
No external bypass capacitor is needed for
achieving the low noise level of 30 µVrms. In
addition to the noise levels, MAS9162 excels in
dropout voltage (95 mV typical at 50 mA) and in
start-up time (typically 10 µs from start-up to within
±1% of VOUT(NOM)).
The Equivalent Series Resistance (ESR) range of
output capacitors that can be used with MAS9162 is
very wide. This ESR range from a few mΩ up to a
couple of Ohms combined with no minimum output
)($785(6
current requirement makes the usage of MAS9162
easier and low in cost. Also the minimum output
capacitance requirement is very low. This combined
with very short start-up time makes it possible to
switch the regulator off and on even in timing critical
and/or noise sensitive applications.
An internal thermal protection circuit prevents the
device from overheating. Also the maximum output
current is internally limited. In order to save power
the device goes into sleep mode when the regulator
is disabled.

tantalum capacitor is used, it
should be checked that the
surge current rating is
sufficient for the application.
3. In the case that the
inductance between a EDWWHU\
