Abstract: A linear regulator includes a drive circuit having an input and an output, with the output configured to drive a control terminal of a power transistor for the delivery of a load current. An error amplifier functions to amplify a difference between a reference signal and a feedback signal to generate an error signal at the input of the drive circuit. A compensation circuit includes a series circuit formed by a compensation capacitor and a variable resistance circuit, where the series circuit is coupled to the input of the drive circuit. A current sensing circuit operates to sense the load current. The resistance of the variable resistance circuit is varied in response to the sensed load current.

Abstract: An oscillator circuit operates to selectively charge and discharge a capacitance with a charging circuit. An inverting circuit includes a first transistor, second transistor, third transistor and fourth transistor having source-drain paths coupled in series. The second and third transistors are connected as an inverter with an input coupled to the capacitance and an output. A feedback loop couples the output of the inverter to an input of the charging circuit. A first shunting transistor is configured to selective shunt across the first transistor in response to a first logic state of a feedback signal in the feedback path. A second shunting transistor is configured to selective shunt across the fourth transistor in response to a second logic state of the feedback signal in the feedback path.
