Abstract
A voltage regulator (15) utilizes a first current source (31) and a second current source (32) to form a reference current to limit current flow through an output transistor (13) during a start-up period. After the start-up period expires, the first current source (31) is disabled and the voltage regulator (15) controls the output voltage produced by the output transistor (13) instead of controlling the current flow through the output transistor (13).
