Three types of output regulator circuit using MIC5157

MIC5157 can be formed with the 3.3 V, 5.0 V and 12V linear regulator, composed by the three regulated output voltage regulator circuit as shown. When MICSl57 3.3 V to 2 feet that is connected to the S-side-side (source), the output to the 3.3 V fixed output; when the MIC5157 is 5.0 V to 1 foot end to the S-side (source), the output to 5.0 V fixed output (when 2 feet vacant); when the MIC5157 2 feet and 1 feet are vacant, the output on the 12V fixed output.
(A) 3.3 V output is not controllable; (b) 3.3 V output controllable; (c) 5.0 V output is not controllable;
(d) 5.0 V output controllable; (e) 12 V output is not controllable; (f) controllable l2 V output
