NOTE:

Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA.

Vin1 is the input voltage at which the output voltage becomes 98% of Vout1 after gradually decreasing the input voltage.

EXPLANATION

BL8563 series is a group of positive voltage output, low noise, low power consumption, low dropout

voltage regulator.

BL8563 can provide output value in the range of 1.0V~4.5V every 0.1V step. It also can be customized on

command.

BL8563 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver

module.

BL8563 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%.
