Note 2:
Guaranteed by design. Not production tested.
Note 3:
Not tested; guaranteed by layout. Maximum output current may be limited by thermal capability to a lower value.
Note 4:
V
TARGET
is the set output voltage determined by V
REFIN
, FBSEL0, and FBSEL1.
Note 5:
Specifications to -40°C are guaranteed by design, not production tested.
