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

reliability and result in failures not covered by warranty.

NOTES:

5. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

6. For JC, the “case temp” location is taken at the package top center.

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 + 0.5V) to 6.5V with a minimum VIN of 2.3V; CIN = 1µF;

CO = 1µF. Boldface limits apply over the operating temperature range, -40°C to +85°C.
