摘要: A circuit and method for providing voltage regulation that operates with relatively low noise, power, fast start up dropout. The invention includes a constant reference is coupled to amplifier which amplifies the selectable level. output of provided an integrated pass noise filter suppresses at least generated by amplifier. inverting input error amplifier, whose non-inverting (VOUT). Also, gate transistor between (VIN) (VOUT) invention.
