BL8566  
Dual 300mA High PSRR LDO  
FEATURES  
DESCRIPTION  
Two low dropout voltage regulators  
300mA output current for each LDO  
20uA operating supply current per LDO  
Low 47uVRMS output noise  
Standby Mode: 0.1uA  
Low 160mV dropout at 300mA load  
73dB PSRR at 100Hz  
Excellent Line regulation: 0.05%/V  
Independent Shutdown controls  
1.5V to 4.5V Factory-Preset Output  
Output Current Limit  
The BL8566 is a dual,low-noise,low-  
dropout regulator delivering at least 300mA 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 1.5V to 4.5V.Typical  
output noise is 47uVrms,and PSRR is 73dB  
at 100Hz. The BL8566 includes two  
independent logic-controlled shutdown inputs  
and allows the output of each regulator to be  
turned of independently.  
High Accuracy: ±2% (±1% customized)  
The BL8566 includes high accuracy  
voltage reference, error amplifier, current limit  
circuit and output driver module.  
APPLICATIONS  
Cellular phones  
The BL8566 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%.  
Cordless phones and radio  
communication equipment  
Battery Powered equipment  
Notebook and hand-hold equipment  
Wireless LAN  
GPS receivers  
The BL8566 is available in SOT-23-6  
package which is lead(Pb)- free
