Its application circuit is very simple, which only needs two outside capacitors. It is composed of these modules: high accuracy voltage reference, current limit circuit, error amplifier, output driver and power transistor. Current Limit module can keep chip and power system away from danger when load current is more than 250mA. A6250A uses trimming technique to as sure the accuracy of output value within ±2%, at the same time, temperature compensation is elaborately considered in this chip, which makes A6250A’s temperature coefficient within 100ppm/℃
