BL8074 800mA Ultra-Low Vin Low Dropout Voltage Linear Regulator GENERAL DESCRIPTION FEATURES BL8074 series are a group of positive voltage output, high precise, and low power consumption voltage regulator. Voltages are selectable in 100mV steps within a range of 1.2V to 5.0V. It also can be customized on command. BL8074 series have 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%. APPLICATIONS BL8074 series are available in SOT-89-3 package, which is lead (Pb)- free.
