Overview

L5965 is a multiple voltage regulator composed by two battery compatible BUCK preregulators (one of which is a controller), two BUCK post regulators with internal compensation, one BOOST, one LDO and a precise voltage reference regulator. All the regulators, except the BUCK1 pre-regulator, have internal power switches.
