产品简介

BL8569 dual,low-noise,low-dropout regulator delivers at least 500mA 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 1.2V to 4.5V. The BL8569 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. BL8569 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. BL8569 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimmingue to guarantee output voltage accuracy within±2%. BL8569 is available in SOT-23-6 package which is lead(Pb)- free
