BL8069

BL8069 REV1.0-Revised DEC 2007 600mA High PSRR, Low Dropout Voltage Linear Regulator DESCRIPTION BL8069 series is a group of positive voltage output, low noise,low power consumption, low dropout voltage regulator. BL8069 can provide output value in the range of 1.5V~4.5V every 0.1V step. It also can be customized on command. BL8069 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module with discharge capability. BL8069 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%. BL8069 is available in SOT-89-3 packages which is lead free.
