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
engineer must take this into account when considering the reference voltage after assembly.
Electrical Specifications V_IN = 5V (2.5V option), I_OUT = 0, unless otherwise specified. Boldface limits apply over the operating
temperature range,-40°C to +125°C.

NOTES:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
8. V_IN-V_OUT measured at the point where V_OUT drops 1mV from the nominal measured value.
