20140145695 | STARTUP CONTROL CIRCUIT IN VOLTAGE REGULATORS AND RELATED CIRCUITS - Aspects of the present disclosure are directed towards apparatus useful for controlling low drop out linear regulators during startup. A voltage regulator device can generate a regulated output voltage from an input voltage and in response to a reference voltage that has, during a startup period, a delayed ramp up relative to a corresponding ramp up of the input voltage. An error circuit generates an error signal in response to a comparison between the output voltage and the reference voltage. An output circuit includes a power transistor that is activated in response to the error signal. A startup control circuit can override, during the startup period for the voltage regulator device, the error signal and thereby counteract activation of the power transistor. | 05-29-2014 |
