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:
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.
6. Post-reflow drift for the ISL71091SEH20 devices can exceed 100µV based on experimental results with devices on FR4 double sided boards. The
engineer must take this into account when considering the reference voltage after assembly.
Electrical Specifications for Flatpack VIN = 5V, IOUT = 0mA, CL = 1µF and CCOMP = 0.001µF unless otherwise specified. Boldface
limits apply across radiation and the operating temperature range, -55°C to +125°C.
