(4) The part is not short circuit protected and is not recommended for operation with low resistive loads. Typical sourcing and sinking output
current curves are provided in the Typical Performance Characteristics and should be consulted before designing for heavy loads.

(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlations using
Statistical Quality Control (SQC) method.
(2) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on
shipped production material.
(3) Positive current corresponds to current flowing into the device.
