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 appears on the output of the linear

regulator when both outputs are in a static load condition.
