The CS8121 design optimizes supply  
rejection by switching the internal  
bandgap reference from the supply  
input to the regulator output as soon as  
the nominal output voltage is achieved.  
Additional on chip filtering enhances  
rejection of high frequency transients  
on all external leads.
