ELECTRICAL CHARACTERISTICS (continued)
(V
values are at T
Note 1: All devices are 100% production tested at T
Note 2: This specification does not include sense resistor tolerance and ground error.
Note 3: Dropout is measured as follows: R
Note 4: OUT’s current regulation varies with load across REG (see the Typical Operating Characteristics ).
Note 5: Overtemperature protection does not function if the output of the 5V reference (REG) is shorted to ground.
Note 6: Guaranteed by design, not production tested.
