Description
SE1122 is a low dropout positive fixed-mode regulator
with minimum of 1A output current capability. The
product
is
specifically
designed
to
provide
Features
1.3V typical dropout at full load current
Fixed 1.2V± 2% output voltage
Fast transient response
Output current limiting
Built-in thermal shutdown
Good noise rejection
Rugged 2KV ESD withstand capability.
Available in SOT223 Packages.
RoHS Compliant and 100% Lead (Pb)-Free
well-regulated supply for low voltage IC applications
such as high-speed bus termination and low current
1.2V logic supply. SE1122 is also well suited for other
applications
such
as
VGA
cards.
SE1122
is
guaranteed to have a typical 1.3V dropout at full load
current making it ideal to provide well-regulated
outputs of 1.2 output voltage with 2.7V input voltage
supply.
