Voltage regulator circuit

摘要

The circuit includes a voltage divider connected between two input terminals (E1, E2) and a smoothing capacitor (C11) connected between two output terminals (A3, A4). One of the input terminals (E2) is directly connected to one of the output terminals (A4). A switchable current source is connected between the first input terminal (E1) and the first output terminal (A3). The voltage divider includes a capacitive branch (R11, C10). A differential amplifier (OP) is provided, having a first input (+) connected to the output voltage of the voltage divider, a second input (-) connected to a reference voltage, and an output connected to the first output terminal of the circuit.
