Notes:
a.V
IN UVLO
is programmable using a resistor divider from V
IN
to ENL to A
GND
. The ENL voltage is compared to an internal reference.
b.Guaranteed by design.
c.The switch-over threshold is the maximum voltage diff erential between the V
LDO
and V
OUT
pins which ensures that V
LDO
will internally
switch-over to V
OUT
. The non-switch-over threshold is the minimum voltage diff erential between the V
LDO
and V
OUT
pins which ensures that
V
LDO
will not switch-over to V
OUT
.
d.The LDO drop out voltage is the voltage at which the LDO output drops 2 % below the nominal regulation point.
