Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VIN = VSHDN = 3.3V, 3/5 = GND, CX = 0.22µF, COUT = 10µF (see Applications Information section to use smaller capacitors),
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: Electrical specifications are measured by pulse testing and are guaranteed for a junction temperature within the operating
temperature range, unless otherwise noted. Limits are 100% production tested at TA = +25°C. Limits over the entire operat-
ing temperature range are guaranteed through correlation using Statistical Quality Control (SQC) methods and are not pro-
duction tested.
