reliability and result in failures not covered by warranty.

NOTES:

4.

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

5. For

JC, the “case temp” location is the center of the ceramic on the package underside.

Electrical Specifications for Flatpack V

IN = 5V, IOUT = 0mA, CL = 1µF and CCOMP = 0.001µF unless otherwise specified. Boldface

limits apply after radiation at +25°C and across the operating temperature range, -55°C to +125°C without radiation, unless otherwise specified.
