Zusammenfassung:	The present subject matter relates to an electronic system (fig. 2) comprising gated circuitry (104), a first regulator circuit (HP-208) directly coupled to the gated circuitry (104), always-on circuitry (202), a second regulator circuit (LP-210) directly coupled to the always-on circuitry (202), and a switch circuit (206) coupled between an output of the first regulator circuit (HP_208) and an output of the second regulator circuit (LP-210). The always-on circuitry (202) includes control logic configured to activate the second regulator circuit (LP-210) and deactivate the first regulator circuit (HP-208) and the switch circuit (206) in a sleep mode and activate the first regulator circuit (HP-208) and the switch circuit (206) in an active mode.
