CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions can adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

4.

JA is measured in free air with the component mounted on a high effective thermal conductivity test board with direct attach features. See TB379.

5.

JC, case temperature location is at the center of the exposed metal pad on the package underside.

Electrical Specifications Unless otherwise noted, all parameter limits are established over the recommended operating conditions and

the typical specification are measured at the following conditions unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are

at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to +85°C.
