AiT Semiconductor Inc. www.ait-ic.com A6201A CMOS LOW DROPOUT REGULATOR (LDO) 250mA LOW CONSUMPTION LINEAR REGULATOR REV1.0 - AUG 2018 RELEASED - - 1 - DESCRIPTION FEATURES A6201A series is a group of positive voltage output, low power consumption, low dropout voltage, three terminal regulator. It can provide 200mA output current when input / output voltage differential drops to 418mV (V OUT= 3.3V), And i t also provides foldback short-circuit protection and output current limit function. The very low power consumption of A6201A (IQ=3uA) can greatly improve natural life of batteries. A6201A can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customized on command. A6201A includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. A6201A has well load transient response and good temperature characteristic, And it uses trimming technique to guarantee output voltage accuracy within±2%. The A6201A is available in SOT-23 and SOT89-3 Packages

AiT Semiconductor Inc. www.ait-ic.com A6201A CMOS LOW DROPOUT REGULATOR (LDO) 250mA LOW CONSUMPTION LINEAR REGULATOR REV1.0 - AUG 2018 RELEASED - - 7 - 7. Load transient response IOUT=1mA~100mA, Ch2—VOUT, Ch4—Iout EXPLANATION A6201A 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 500mA. A6201A uses trimming techni que to assure the accuracy of output value within±2%, at the same time, temperature compensation is elaborately considered in this chip, which makes A6201A’s temperature coefficient within 100ppm/℃。
