Abstract
A voltage regulator ( ) utilizes a first current source ( ) and a second current source ( ) to form a reference current to limit current flow through an output transistor ( ) during a start-up period. After the start-up period expires, the first current source ( ) is disabled and the voltage regulator ( ) controls the output voltage produced by the output transistor ( ) instead of controlling the current flow through the output transistor ( ).
