摘要： Systems, methods and circuits for regulator minimum load control. In one particular case, a system is provided that includes a load control circuit and a switched load. The load control circuit includes a reference current, and a sense current representative of a load current. In addition, the load control circuit includes a comparator circuit that drives a control signal in response to a comparison between the reference current and the sense current. The switched load is electrically coupled to a load voltage signal to provide loading to the load voltage signal. The switched load is operable to switch between a first loading factor and a second loading factor in response to the control signal.

摘要： A method and apparatus for a Regulator that automatically configures to work in either SMPS mode or linear mode are disclosed. in one embodiment, the method includes inputting a constant current source to a CBoot_pin for a first predetermined amount of time upon enabling an autodetect circuit by a Regulator control circuit. The CBoot voltage at the CBoot_pin is hen determined to see if the CBBoot voltage at the CBoot_pin is above a predetermined CBoot voltage for a second predetermined amount of time. The Regulator is then switched to operate in SMPS mode if the CBoot voltage is substantially continuously above the predetermined CBoot voltage for a second predetermined amount of time. The SMPS is operated in linear mode if the CBoot voltage is substantially continuously below or equal to the predetermined CBoot voltage for a second predetermined amount of time.

摘要： A circuit (10, 100) is used to perform voltage regulation. In one embodiment, a voltage regulator (11) is used in conjunction with an output transistor (24) to form a circuit (10) which operates to regulate the voltage drop from a first node (30) to a second node (28). This second node (28) may be used to provide power to circuitry (27). The areas of several transistors (20-25) in circuit (10) may be adjusted so that negative and positive temperature coefficients may be balanced such that the circuit (10) behaves as desired over a range of voltages and temperatures. Note that in one embodiment, circuit (10) is a 2-terminal device.
