BL8071

BL8071
1.5A Linear Regulator
GENERAL DESCRIPTION
FEATURES
BL8071 series are a group of positive voltage
output, high precise, and low power consumption
voltage regulator. Voltages are selectable in 100mV
steps within a range of 1.2V to 5.0V. It also can be
customized on command.







BL8071 series have excellent load and line
transient response and good temperature
characteristics, which can assure the stability of
chip and power system. And it uses trimming
technique to guarantee output voltage accuracy
within ±2%.
APPLICATIONS





BL8071 series are available in SOT-223 package,
which are lead (Pb)- free.
