BL8569 Dual 500mA High PSRR Linear Regulator DESCRIPTION FEATURES • • • • • • • • • • • 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. Two low dropout voltage regulators 500mA output current for each LDO Low output noise (50uVRMS) Low dropout Voltage:0.08V@150mA(Typ) Standby Mode: 0.1uA High Ripple Rijection:72dB@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 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 TYPICAL APPLICATION Cellular phones Cordless phones and radio communication equipment Battery Powered equipment Notebook and hand-hold equipment Wireless LAN GPS receivers ELECTRICAL CHARACTERISTICS PSRR 80 70 PSRR(dB) 60 Vout=3.3V 50 40 30 20 APPLICATION HINTS 10 NOTE: Input capacitor (Cin=1uF) and Output capacitor (Cout=1uF/3.3uF) are recommended in all application circuit. www.belling.com.cn 0 0.01 0.1 1 10 Freq(KHz) 1 100 1000 BL8569 ORDERING INFORMATION PIN CONFIGURATION BL8569 □ 1 □ 2 □ 3 □ 4 □ 5 Product Classification Code Description 1 □ Temperature&Rohs: C:-40~85°C ,Pb Free Rohs Std.
