Abstract
A hybrid voltage regulator includes a shunt circuit, a shunt feedback circuit, a pass circuit, and a bias controller. The bias controller is configured to control the pass circuit. The hybrid voltage regulator may also include a current source. This hybrid voltage regulator reduces current consumption at low load conditions (improving power efficiency and battery life, particularly for CMOS based regulators), and also provides wideband power supply rejection and fast transient response.
