摘要： A negative output regulator circuit (24) is provided with clamp circuits CLP (X1, X2, Q1, Q2), which detect a current generated when the output of a negative voltage (VM) is stopped and fixing the voltage of an output end (T2) at a prescribed value. Generation of a positive voltage at an output terminal is suppressed without increasing chip size nor making the sequence complicated.

摘要： An electronic circuit includes a semiconductor device which has an internal circuit that uses a positive power supply voltage and a negative power supply voltage, and which controls the operation of the above-mentioned internal circuit by an external input. The semiconductor device includes an input signal detection circuit that operates using a voltage that is input into the external input, and a signal output circuit which outputs a signal that controls the negative power supply voltage applied to the internal circuit in accordance with an output of the input signal detection circuit. The circuit can switch a negative-side circuit on and off without depending on a positive power supply voltage and also without depending on the order of starting a positive power supply voltage and a negative power supply voltage.
