Abstract
This paper introduces a low dropout (LDO) voltage regulator with an integrated current monitor, which sets a new performance benchmark in terms of RF immunity. Compared to classic topologies the proposed circuit succeeds in a very high robustness against RF disturbances which are superimposed into the regulator's battery voltage (VS) pin and output (OUT) pin. The proposed circuit was designed using a HV-BiCMOS technology for automotive applications. Circuit theory is explained in detail and the proposed approach is confirmed by RF immunity measurements.
