BL8062
250mA Low Consumption Linear Regulator
DESCRIPTION
BL8062 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 (Vout= 3.3V),
And it also provides
foldback short-circuit
protection
and
output current limit function. The
very low power consumption of BL8062
(Iq=3uA)can greatly improve natural life of
batteries.
BL8062 can provide output value in the range of
1.2V~5.0V in 0.1V steps. It also can customized
on command.
BL8062 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module.
BL8062 has well load transient response and
good temperature characteristic, And it uses
trimming technique to guarantee output voltage
accuracy within±2%.

BLOCK DIAGRAM
EXPLANATION
BL8062 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.
BL8062 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 BL8062’s temperature
coefficient within 100ppm/℃。
