发明名称 Low-dropout regulator and method for voltage regulation
摘要 A low-dropout regulator (1) comprises a differential amplifier (3) with a reference input (5) for applying a reference voltage (VIN), a feedback input (7) and an amplifier output (9). An output transistor (11) has a control connection (13) connected to the amplifier output (9), and a control section connected between a first supply potential terminal (VDD) and a voltage output (15) of the low-dropout regulator (1). A feedback branch (17) with an RC-parallel connection (19) is coupled between the voltage output (15) and the feedback input (7). A precharge circuit (30) includes a first field effect transistor (31) with a gate (32) coupled to the feedback input (7) and is configured to precharge the RC-parallel connection (19) to a threshold voltage (VTH) of the first field effect transistor (31).
