DESCRIPTION
FEATURES
Low Power Consumption: 2.0uA（Typ.）
Maximum Output Current: 250mA
Small Dropout Voltage
A6201 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 420mV (VOUT= 3.3V), And it
also provides foldback short-circuit protection
and output current limit function. The very low
power consumption of A6201 (IQ=2.0uA) can
greatly improve natural life of batteries.
A6201 can provide output value in the range of
1.1V~5.0V in 0.1V steps. It also can customized
on command.

DETAILED INFORMATION
A6201 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.
A6201 uses trimming technique to assure the accuracy of output value within±2%, at the same time,
temperature compensation is elaborately considered in this chip, which makes A6201’s temperature
coefficient within 100ppm/℃。
