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 LT1762 regulators are tested and specified under pulse
load conditions such that T
J
≈ T
A
. The LT1762 is 100% tested at 25°C.
Performance at –40°C and 125°C is assured by design, characterization
and correlation with statistical process controls.
Note 3:
The LT1762 (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 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 LT1762
(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.
Note 6:
Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a specified 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)
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 flows into the ADJ pin.
Note 9:
SHDN
pin current flows 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 flows into the OUT
