摘要： The present application relates to a power supply module which is operable in a switch mode and in a linear mode. The power supply module includes a detector for detecting the presence of an inductor at an output node of the power supply module If an inductor is detected, the detector outputs a signal indicating the presence of the inductor, and the power supply module selects the switch mode as its operating mode. If no inductor is detected, the detector outputs a signal indicative of the absence of an inductor and the power supply module selects its linear mode as its operating mode.

摘要： A low drop-out voltage regulator having a pass device (Mp), an error amplifier (M1-M51) and a double regulation loop including DC feedback loop (R1, R2) and an AC feedback loop (Rf, Cf) including a high pass filter (Cf). Combining these two loops creates an ultra low frequency internal pole which makes the regulator stable substantially independent of the output bypass capacitor's value. This provides the following advantages: allows the use of very low bypass capacitors; allows to extend the PSRR frequency behavior; allows an increase in the regulator's efficiency (reduced power consumption on heavy loads).

摘要： A voltage regulator for providing a voltage regulated output to a load comprises a first loop and a second loop. The first loop comprises a first active device coupled to a first pass device and configured to provide a first, relatively high current output to the load. The second loop comprises a second active device coupled to a second pass device and configured to provide a second, relatively low current output to the load.In this manner, when the inventive concept is applied to low drop-out regulators, the provision of two independent loops reduces dramatically the quiescent current provided by the voltage regulator under low load conditions.
