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. θ 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 θ JC , the “case temp” location is taken at the package top center.
6. Post-reflow drift for the ISL21090 devices can exceed 100μV to 1.0mV based on experimental results with devices on FR4 double sided boards. The
system engineer must take this into account when considering the reference voltage after assembly.
Electrical Specifications V IN = 5V (1.25V option), I OUT = 0, C L = 0.1μF and C C = 0.01μF, unless otherwise specified. Boldface limits apply
over the operating temperature range, -40°C to +125°C.
