Note 2: The LT1763 regulators are tested and specified under pulse load
conditions such that T ≈ T . The LT1763 is 100% tested at T = 25°C.

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 5µA DC load on the output.
Performance at –40°C and 125°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
