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 LT1761 regulators are tested and speci?ed under pulse load
conditions such that T J ≈ T A . The LT1761E is 100% production 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
LT1761I is guaranteed over the full –40°C to 125°C operating junction
temperature range. The LT1761MP is 100% tested and guaranteed over
the –55°C to 125°C operating junction temperature range.
Note 3: The LT1761 (adjustable versions) are 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 LT1761
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
(whichever is greater) and a current source load. This means the device
is tested while operating in its dropout region or at the minimum input
voltage speci?cation. 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 LT1761, LT1761-1.2, LT1761-1.5, LT1761-1.8 and
LT1761-2 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 V IN = 2.3V, whichever is greater.
(adjustable version) is tested and speci?ed 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.
