CAT7105
General Description
The CAT7105 is a high efficiency step-down DC/DC
converter series with the output current up to 2A and
integrates a low on resistance NMOS at the high side.
Included on the substrate with the features listed is a
high performance trans-conductance error amplifier
that provides tight voltage regulation and accuracy
under transient conditions. An under voltage lockout
circuit is built in to prevent start-up until the input
voltage reaches to 4.75V. In addition, it features an
over-current protection and thermal shutdown. The
CAT7105 is available in the SOP8 package.
