BL8559
2A Linear Regulator
GENERAL DESCRIPTION
BL8559 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 3.6V. It also can be customized on
command.
BL8559 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%.
BL8559 series are available in SOT-223
package, which is lead (Pb)- free.
