Abstract

A low drop out, LDO, voltage regulator circuit is that includes a high gain amplifier configured to receive a current biasing signal and arranged to regulate the voltage supply signal and output a regulated voltage supply signal. A regulation adjustment circuit is operably coupled to an output of the high gain amplifier and includes a comparator configured to compare the output regulated voltage supply signal with a threshold, wherein an output of the comparator is configured to perform one of: (i) supply a dynamic current boost to the LDO current biasing signal, in response to the regulated voltage supply signal voltage dropping below the threshold; (ii) activate a dynamic current pull down circuit to reduce an over voltage output of the LDO voltage regulator circuit in response to the regulated voltage supply signal voltage exceeding the threshold.
