all possible combinations of input voltage and output current. When
operating at maximum input voltage, the output current range must be
limited. When operating at maximum output current, the input voltage
range must be limited.
Note 5:
To satisfy requirements for minimum input voltage, the LT1763
(adjustable version) is tested and specified for these conditions with an
external resistor divider (two 250k resistors) for an output voltage of
2.44V. The external resistor divider will add a 5
μ
A DC load on the output.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LT1763 regulators are tested and specified under pulse load
conditions such that T

C is assured by design, characterization
and correlation with statistical process controls.
Note 3:
The LT1763 (adjustable version) is tested and specified for these
conditions with the ADJ pin connected to the OUT pin.
Note 4:
Operating conditions are limited by maximum junction
temperature. The regulated output voltage specification will not apply for
