摘要：A band-gap filter circuit is disclod for u in a voltage regulator. A capacitor charger (or “cap charger”) circuit quickly charges a filter capacitor when power is
ck是什么意思applied to the voltage regulator circuit. At start-up, the cap charger begins charging the
filter capacitor. Once an output node equals or nearly equals the voltage at the input node, the cap charger shuts off. The circuit provides a very fast turn-on time, reaching 95% of its steady state value within 200 microconds, thus overcoming the long turn-on times associated with other designs. The prent invention may be utilized in power nsitive applications, such as cellular telephones, that wish to shut off the voltage regulator in order to conrve power.
