Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
ELECTRICAL CHARACTERISTICS
Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature
range.
(TJ = 25°C, VIN = VO(NOM) + 1V, IL = 10 mA, COUT = 2.2μF, VSD = VIN-0.3V, unless otherwise specified.)
