LT1764A LINER [Linear Technology], LT1764A Datasheet - Page 4

• Manufacturer Part Number: LT1764A
• Description: 1.1A, Low Noise, Low Dropout Linear Regulator
• Manufacturer: LINER [Linear Technology]

ELECTRICAL CHARACTERISTICS
LT1965
Note 9: ADJ pin bias current fl ows into the ADJ pin.
Note 10: ⎯ S ⎯ H ⎯ D ⎯ N pin current fl ows into the ⎯ S ⎯ H ⎯ D ⎯ N pin.
Note 11: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current fl ows into the OUT
pin and out of the GND pin.
Note 12: For the LT1965, the minimum input voltage specifi cation limits
the dropout voltage under some output voltage/load conditions.

Note 13: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature is active.
Continuous operation above the specifi ed maximum operating junction
temperature may impair device reliability.
