Notes:
() VIN UVLO is programmable using a resistor divider from VIN to ENL to AGND. The ENL voltage is compared to an internal reference.
(2) Guaranteed by design.
(3) For VDDA less than 4.5V, the On-Time may be limited by the VDDA supply voltage and by V
IN
. See the TON Limitations and VDDA Supply
Voltage section in the Applications Information.
(4) The ENL pin will enable the LDO with .0V typical. The ENL pins VIN ULVO function will disable the switcher unless the ENL pin exceeds the
V
IN
 UVLO Threshold (typical 2.5V).
(5) The switch-over threshold is the maximum voltage differential between the VLDO and VOUT pins which ensures that VLDO will internally
switch-over to VOUT. The non-switch-over threshold is the minimum voltage differential between the VLDO and VOUT pins which ensures
that VLDO will not switch-over to VOUT.
(6) The LDO drop out voltage is the voltage at which the LDO output drops 2% below the nominal regulation point.
