Abstract
The present invention relates in one aspect to a DC linear voltage regulator circuit for generating a regulated DC output voltage based on a DC input voltage. The DC linear voltage regulator circuit comprises a DMOS pass transistor comprising drain, gate, source and bulk terminals wherein the drain terminal is connected to a regulator output which is configured to supply the regulated DC output voltage and the source terminal is connected to a regulator input for receipt of the DC input voltage. The DC linear voltage regulator circuit comprises a switchable leakage prevention circuit, connected to the bulk terminal of the DMOS pass transistor, and configured to automatically detect and interrupt a flow of leakage current from the regulator output to the bulk terminal.
