MaximumRatings

(Above which the useful life may be impaired.

For user guidelines, not tested.)

Voltage range applied to any output in the

Voltage range applied to any output in the

package K .......... 48°C/W

1. Input & output negative-voltage ratings may be exceeded if the

input and output curent rating are observed.

2. Output positive-voltage rating may be exceeded up to 4.6V

maximum if the output current rating is observed.

3. The package thermal impedance is calculated in accordance with

JESD51.

Notes:

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.
