Note 1: Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.
Note 2: The output current may be increased to 100mA by changing the RTSETOP resistor for the CQ (PLCC) package option only. See equation (1) on page 9. The increased
current option is not available for the CH (TQFP) package option.
