Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested.) V oltage range applied to any output in the Notes: 1. Input negative voltage & output voltage ratings may be exceeded if the input and output current rating are observed. 2. This value is limited to 3.6V maximium. 3. The package thermal impedance is calculated in accordance with JESD 51. 4. Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Pin Configuration Note: 1.
