VER 1.2 3 ACE507C 200mA Low Consumption Linear Regulator Explanation： ACE507C is a series of low dropout voltage and low power consumption three pins regulator. 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 200mA. ACE507C uses trimming technique to assure the accuracy of output value within±2%, at the same time, temperature compensated is elaborately considered in this chip, which makes ACE507C’s temperature coefficient within 100ppm/℃.
