BL8559

BL8559 GENERAL DESCRIPTION BL8559 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 3.6V. It also can be customized on command. BL8559 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%. BL8559 series are available in SOT-223 package, which is lead (Pb)- free. 2A Linear Regulator FEATURES Low Quiescent Current: 26uA at 5V High PSRR: 60dB range to 1KHz Low Output Noise: 44uVRMS Low Dropout: 430mV at 1.5A load Maximum output current: 2.5A Highly Accurate: ±2% Low ESR Ceramic Capacitor Compatible APPLICATIONS Reference Voltage Source Battery Powered Equipment PC Peripherals Wireless Devices Instrumentation TYPICAL APPLICATION IN Cin BLLC81545966 VDD VOUT GND OUT Cout NOTE: Input capacitor (Cin=1uF) and Output capacitor (Cout=4.7uF) are recommended in all application circuit (Low ESR ceramic capacitor is available).
