Abstract
Provided is a signal isolator with reduced power loss. The signal isolating circuit comprises an input stage and an output circuit that is connected downstream thereof and which includes a linear regulator. The linear regulator comprises an operational amplifier and a switching regulator, wherein an input of the switching regulator is connected to an output of the operational amplifier and an output of the switching regulator is fed back to a first input of the operational amplifier. The operational amplifier regulates the switching regulator such that the switching regulator provides at its output an output measuring signal for a load that corresponds to the input measuring signal.
