Claim Text:
1. A load switch comprising: a pass element comprising a first node and a second node, the pass element configured to be coupled to a power supply and a load, and the pass element further configured to electrically couple the power supply with the load during an ON-state of the pass element and electrically decouple the power supply from the load during an OFF-state of the pass element, the first node positioned to be coupled to the power supply and the second node positioned to be coupled to the load; a level-shift circuit comprising a first transistor and a pull-up resistor, the first transistor comprising a first terminal, a second terminal and a third terminal, the pull-up resistor coupled between the first node and the first terminal, the first transistor and the pull-up resistor configured to generate a level-shifted signal at the first terminal in response to an enable signal at the third terminal, and to enable the ON-state and the OFF-state of the pass element based on the level-shifted signal; and a low-resistance active path coupled in parallel with the pull-up resistor for shunting the pull-up resistor in the OFF-state by providing a path for a leakage current of the first transistor in the OFF-state.
