Abstract
A low-dropout regulator () comprises a differential amplifier () with a reference input () for applying a reference voltage (VIN), a feedback input () and an amplifier output (). An output transistor () has a control connection () connected to the amplifier output (), and a control section connected between a first supply potential terminal (VDD) and a voltage output () of the low-dropout regulator (). A feedback branch () with an RC-parallel connection () is coupled between the voltage output () and the feedback input (). A precharge circuit () includes a first field effect transistor () with a gate () coupled to the feedback input () and is configured to precharge the RC-parallel connection () to a threshold voltage (VTH) of the first field effect transistor ().
