2995f

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: All currents into pins are positive; all voltages are referenced to

GND unless otherwise noted.

Note 3: Remote diode temperature, not LTC2995 temperature.

Note 4: Guaranteed by design and test correlation.
