Note 2: Limits at -40°C are guaranteed by design and characterization; not production tested.
Note 3: Guaranteed minimum operating voltage is 3.5V on V
IN
falling only.
Note 4: Guaranteed by design and not production tested.
Note 5: The boost converter disable threshold (V
BST_DIS
) is a static measurement. Internal comparator delay may cause a higher
disable level.
Note 6: The continuous maximum output current from the LDO is guaranteed according to the maximum power dissipation imposed
by the package thermal constraints.
Note 7: Maximum output adjustable value is conditioned by the maximum adjustable BSOUT Output Voltage Range minus the
maximum dropout across the pass transistor.
Note 8: Dropout voltage is defined as (V
BSOUT
- V
OUT
) when V
OUT
