Notes:
1. When the LIN_EN pin is LOW, the linear regulator output is set with external resistors. When the LIN_EN pin is HIGH, the
linear regulator is disabled and will exhibit no output voltage. Please refer to the Application Section for output voltage
selection information.
2. Setpoint accuracy is the initial output voltage variability under the specified conditions. The matching of the external resistors
will have a major influence on this parameter.
3. Cumulative DC accuracy includes setpoint accuracy, temperature drift, line and load regulation.
4. Crosstalk is defined as the amount of switching noise from the switch-mode regulator that
regulator when both outputs are in a static load condition.
