NOTE:

Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=500mA.

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

Explanation

BL8565 series is a group of positive voltage output, low noise, low power consumption, low

dropout voltage regulator.

BL8565 can provide output value in the range of 1.5V~4.5V every 0.1V step. It also can be

customized on command.

BL8565 includes high accuracy voltage reference, error amplifier, current limit circuit and output

driver module.

BL8565 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%.
