Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT1763 regulators are tested and speci?ed under pulse
load conditions such that T J ? T A . The LT1763 (C grade) is 100% tested
at T A = 25°C; performance at –40°C and 125°C is assured by design,
characterization and correlation with statistical process controls. The
LT1763 (I grade) is guaranteed over the full –40°C to 125°C operating
junction temperature range. The LT1763 (MP grade) is 100% tested and
guaranteed over the –55°C to 125°C operating junction temperature range.
Note 3: The LT1763 (adjustable version) is tested and speci?ed 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 speci?cation will not apply
for 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 speci?ed for these conditions with an
Note 6: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a speci?ed output current. In dropout, the
output voltage will be equal to: V IN – V DROPOUT .
Note 7: GND pin current is tested with V IN = V OUT(NOMINAL) or V IN = 2.3V
(C, I grade) or 2.35V (MP grade), whichever is greater, and a current
source load. This means the device is tested while operating in its dropout
region. This is the worst-case GND pin current. The GND pin current will
decrease slightly at higher input voltages.
Note 8: ADJ pin bias current ?ows into the ADJ pin.
Note 9: SHDN pin current ?ows into the SHDN pin.
Note 10: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current ?ows into the OUT
pin and out the GND pin.
Note 11: For the LT1763, LT1763-1.5 and LT1763-1.8 dropout voltage will
be limited by the minimum input voltage speci?cation under some output
voltage/load conditions. See the curve of Minimum Input Voltage in the
Typical Performance Characteristics.
Note 12: To satisfy requirements for minimum input voltage, current limit
is tested at V IN = V OUT(NOMINAL) + 1V or 2.3V (C, I grade) or 2.35V
(MP grade), whichever is greater.
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.
