Application Note
TYPICAL CONNECTION DIAGRAMS
LP3971 is flexible for different system configurations. Differ-
ent power domains can be selected based on current and
voltage needs. Additionally Buck2 LDO4 and lDO5 default
enables can be changed for further flexibility. Please note
that LDO1 is recommended to be used for I/Os if RTC
voltage need to track I/O voltage. Also LDO4 and LDO5 has
an own V
IN pin which can be driven from a buck regulator for
higher system efficiency.
