Low Power Consumption:7uA(Typ.)
BL8553 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
470mV(Vout=2.0V)。The very low power
consumption of BL8553(Iq=7uA)can
greatly improve natural life of batteries.

Typical Application Circuit:
:
Application hints:
:
NOTE1 : Input capacitor (Cin=1uF) is
recommended in all application circuit.
Tantalum capacitor is recommended.
NOTE2 : Output capacitor (Cout=1uF) is
recommended in all application to
assure the stability of circuit. Tantalum
capacitor is recommended.
Explanation:
:
BL8553 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 400mA.
BL8553 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 BL8553’s
temperature coefficient within 50ppm/℃。
