Abstract
A voltage regulator includes: an output transistor containing a source connected to an input port and a drain connected to an output port; voltage dividing resistors which are connected between a voltage adjustment port and a ground port, divide an adjustment voltage received at the voltage adjustment port, and output a feedback voltage; a reference voltage circuit which outputs a reference voltage; an error amplifier circuit which controls a gate voltage of the output transistor based on the reference voltage and the feedback voltage; and a disconnection protection circuit which includes a first MOS transistor containing a source connected to the output port and a gate connected to the voltage adjustment port, and detects a disconnection of a bonding wire of the voltage adjustment port.
