VOLTAGE DIVIDER, CONSTANT VOLTAGE CIRCUIT USING SAME, AND TRIMMING METHOD IN THE VOLTAGE DIVIDER CIRCUIT

摘要

is a voltage divider circuit to divide the input voltage the ratio of the partial pressure of generating a predetermined divided voltage , and outputs the divided voltage is disclosed. A voltage divider circuit and the plurality of resistors corresponds to a plurality of resistors connected in parallel are connected to the first resistor circuit and the corresponding fuse are connected in series in parallel to the fuse connected in series , a first resistor connected in series with the second resistor circuit circuit includes . The divided voltage is output from the connection of the first resistor circuit and the second resistor circuit , fuses of the first resistor circuit and the second resistor circuit , trim the combined resistance of the first resistor circuit and the second resistor circuit is constant (trimming ) is .
