CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See

Tech Brief TB379.

JC, “case temperature” location is at the center of the exposed metal pad on the package underside. See Tech Brief TB379.

Electrical Specifications

Unless otherwise noted, all parameters are guaranteed over the operational supply voltage and temperature

range of the device as follows:

TA = -40°C to +85°C; VIN = (VO+1.0V) to 6.5V with a minimum VIN of 2.3V; CIN = 1μF; CO = 1μF;

CBYP = 0.01μF
