ORDERING INFORMATION
DESCRIPTION
The BL8566 is a dual,low-noise,low-
dropout regulator delivering at least 300mA of
continuous output current. The output voltage
for each regulator is set independently by
trimming.Voltages are selectable in 100mV
steps within a range of 1.5V to 4.5V.Typical
output noise is 47uVrms,and PSRR is 73dB
at 100Hz. The BL8566 includes two
independent logic-controlled shutdown inputs
and allows the output of each regulator to be
turned of independently.
The BL8566 includes high accuracy
voltage reference, error amplifier, current limit
circuit and output driver module.
The BL8566 has 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%.
The BL8566 is available in SOT-23-6
package which is lead(Pb)- free
