Electrical Characteristics (continued)
Notes:
(1) V
(2) For VDD less than 4.5V, the on-time may be limited by the VDD supply voltage and by the V
(3) The switch-over threshold is the maximum voltage differential between the VDD and VOUT pins which ensures that LDO will internally switch-
(4) The LDO drop out voltage is the voltage at which the LDO output drops 2% below the no load regulation value.

over to VOUT. The non-switch-over threshold is the minimum voltage differential between the LDO and VOUT pins which ensures that LDO
will not switch-over to VOUT.
IN
UVLO is programmable using a resistor divider from VIN to ENL to AGND pins. The ENL voltage is compared to an internal reference.
