Integrated high slew rate enhancement circuit psr low-dropout linear regulator

The present invention relates to power management techniques. The present invention solves the most low-dropout linear regulator to increase circuit complexity, and reduce the load capacity of the output voltage increases at the expense of noise problem solving output voltage of voltage spikes, provides an integrated high slew rate enhancement circuit PSR low-dropout linear regulator, which technical solutions can be summarized as follows: compared with the conventional the LDO, increasing the slew rate enhancement circuit and a compensation capacitor, and the positive-phase input terminal and the reference voltage source is connected to the inverting input of the error amplifier the gate terminal of the resistor connected to the feedback circuit, the output terminal of the slew rate enhancement circuit connected to an input slew rate enhancement circuit with the output terminal of the regulator, the compensation capacitor and the inverting input terminal of the error amplifier is connected to one end of compensation capacitor the other end is connected to the output terminal. Advantageous effect of the invention is to improve the transient response for low-dropout linear regulator.
