The q denotes specifications which apply over the full operating temperature range, otherwise specifications are TA = 25°C. (Note 2)

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

µA 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 TJ ≈ TA. The LT1763 is 100% tested at TA = 25°C.

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
