Leakage current control for multi-supply voltage regulators

Abstract

Techniques and apparatus for supplying power using a power supply circuit, including leakage current control for multi-supply voltage regulators. One example power supply circuit generally includes a first power supply node, a second power supply node, a third power supply node, and an output node. The power supply circuit also generally includes (i) a first head switch transistor including a source coupled to the first power supply node and including a drain coupled to the output node; (ii) a second head switch transistor including a source coupled to the second power supply node and including a drain coupled to the output node; and (iii) a first transistor including a source coupled to the first power supply node, a gate coupled to the third power supply node, and a drain coupled to a gate of the first head switch transistor.
