DETAILED INFORMATION
Explanation
A6250 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
250mA.
A6250 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 A6250’s temperature
coefficient within 50ppm/℃.
