description The utility model discloses a pulse controllable vehicle voltage regulator, including a reference voltage circuit, a compared circuit, a level detection circuit, a pulse width control circuit and an amplifier circuit. The utility model is characterized in that the reference voltage circuit, the compared circuit, the pulse width control circuit and the amplifier circuit are interconnected in sequence, and the level detection circuit is connected with the compared circuit. Wherein, the pulse width control circuit consists of a resistor, a capacitor and a non-repeated trigger monostable multivibrator integrated circuit and can effectively reduce switching frequency of the power amplifier circuit, reducing self power loss of the regulator, and avoiding the shortcoming of high temperature and easy damage in real sense. The utility model is applicable for manufacture of various automotive voltage regulators.
