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:
1. The maximum voltage rating for the VB pin under continuous operating conditions is 5.5V. All other pins are allowed to operate continuously at
the absolute maximum ratings.
2. θ_JA 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.
3. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Typical values are tested at V_IN = 5.0V and T_A = +25°C, maximum and minimum values are guaranteed over
the recommended operating conditions, unless otherwise noted.
