BL8075
16V 500mA Low Consumption Linear Regulator
DESCRIPTION
BL8075 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator. It can provide 300mA output
current when input / output voltage differential
drops to 600mV (Vout= 3.3V),
and it also
provides
foldback short-circuit protection,
thermal protection
and
output current limit
function. The very low power consumption of
BL8075 (Iq=10uA)can greatly improve natural life
of batteries.
BL8075 can provide output value in the range of
1.2V~5.0V in 0.1V steps. It also can customize on
command.
BL8075 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module.
BL8075 has well load transient response and
good temperature characteristic, And it uses
trimming technique to guarantee output voltage
accuracy within±2%.

EXPLANATION
BL8075 is a series of low dropout voltage and low power consumption 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.
BL8075 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 BL8075’s temperature
coefficient within ±100ppm/℃。
