Abstract
An improved on-chip voltage regulator providing improved reliability by eliminating voltage stresses on critical components, comprising, a reference-signal generating block providing a first-order temperature-compensated voltage-reference signal and a first-order temperature-compensated current-reference signal, an operational-amplifier block providing a regulated voltage, connected to the outputs of said reference signal generating block; a standby protection block receiving an external signal for enabling/disabling said reference-signal generating block and said operational-amplifier block, and; a protection voltage block connected to all said blocks; wherein critical elements of said blocks are connected such that voltage difference between any two terminals is always less than the break down voltage of said critical element.
