SUPPLY SPECIFICATION
LINEAR LOW DROP-OUT REGULATORS (LDOS)
LDO1 is a regulator that can respond to fast transients and is
slated for digital loads and high bandwidth analog loads.
LDO2 is a linear regulator with a similar architecture but has
a slower transient response time with a lower noise perfor-
NO-LOAD STABILITY
The LDOs will remain stable and in regulation with no external
load. This is an important consideration in some circuits, for
example CMOS RAM keep-alive applications.
