ELECTRICAL CHARACTERISTICS
temperature range, otherwise specifications are at T
A
= 25°C. (Note 3)
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:
Absolute maximum input to output differential voltage is not
achievable with all combinations of rated IN pin and OUT pin voltages.
With the IN pin at 22V, the OUT pin may not be pulled below 0V. The total
measured voltage from IN to OUT must not exceed ±22V.
Note 3:
The LT1965 is tested and specified under pulse load conditions
such that T

at –40°C and 125°C is assured by design, characterization, and correlation
with statistical process controls. The LT1965I is guaranteed over the full
–40°C to 125°C operating junction temperature range.
Note 4:
The LT1965 is tested and specified for these conditions with the
ADJ connected to the OUT pin.

Note 5:
Maximum junction temperature limits operating conditions. The
regulated output voltage specification does not apply for all possible
combinations of input voltage and output current. Limit the output current
range if operating at the maximum input voltage. Limit the input-to-output
voltage differential if operating at the maximum output current.
Note 6:
To satisfy minimum input voltage requirements, the LT1965 is
tested and specified for these conditions with an external resistor divider
(bottom 4.02k, top 4.32k) for an output voltage of 2.5V. The external
resistor divider adds 300μA of output DC load current.
Note 7:
Dropout voltage is the minimum input-to-output voltage
differential needed to maintain regulation at a specified output current. In
dropout, the output voltage equals: (V
IN
– V
DROPOUT
)
Note 8:
GND pin current is tested with V

+ 1V and a
current source load. GND pin current increases slightly in dropout. See
GND pin current curves in the Typical Performance Characteristics section.
