BL8569 Datasheet | BELLING

Dual 500m A High PSRR Linear Regulator DESCRIPTION Features BL8569 dual,low-noise,low-dropout regulator delivers at least 500m A of continuous output current. The output voltage for each regulator is set independently by trimming.Voltages are selectable in 100m V 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 trimming technique to guarantee output voltage accuracy within±2%. BL8569 is available in SOT-23-6 package which is lead(Pb)- free - Two low dropout voltage regulators - 500m A output current for each LDO - Low output noise (50u VRMS) - Low dropout Voltage:0.08V@150m A(Typ) - Standby Mode: 0.1u A - High Ripple Rijection:72d B@1000Hz (Typ) - Excellent Line regulation: 0.05%/V - Independent Shutdown controls - 1.2V to 4.5V Factory-Preset Output - Output Current Limit - Highly Accurate: ±2% APPLICATIONS - Cellular phones - Cordless phones and radio munication equipment - Battery Powered equipment - Notebook and hand-hold equipment - Wireless LAN - GPS receivers TYPICAL APPLICATION ELECTRICAL CHARACTERISTICS APPLICATION HINTS NOTE: Input capacitor (Cin=1u F) and Output capacitor (Cout=1u F/3.3u F) are remended in all application circuit.
