ORDERING INFORMATION

DESCRIPTIONBL8566 BL8566

The BL8566 is a dual,low-noise,lowdropout

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
