Description
SE1122 is a low dropout positive fixed-mode regulator
with minimum of 1A output current capability. The
product
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
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.
