DESCRIPTION  
-54dB @ 1MHz  
The BL9165 is designed for portable  
applications with demanding performance  
and space requirements. The BL9165  
performance is optimized for battery-powered  
systems to deliver ultra-low noise and low  
quiescent current. Regulator ground current  
increases only slightly in dropout, further  
prolonging the battery life. The BL9165 also  
works with low-ESR ceramic capacitors,  
reducing the amount of board space  
necessary for power applications, critical in  
hand-held wireless devices. The BL9165  
consumes only 0.1µA current in shutdown  
mode and has fast turn-on time (Typical  
100µs ). The other features include ultra- low  
dropout voltage, high output accuracy, current  
limiting protection, and high ripple rejection  
ratio.  
0.1A Standby Current When Shutdown  
Low Dropout: 240mV@500mA (VOUT=2.8V)  
Wide Operating Voltage Ranges:  
1.8V to 5.5V  
Current Limiting and Short Circuit  
Current Protection  
Thermal Shutdown Protection  
Only 1F Output Capacitor Required for  
Stability  
Fast output discharge  
Available in SOT23-5, SC70-5 and  
DFN1X1-4L Packages  
APPLICATIONS  
Cellular and Smart Phones  
Cordless Telephones  
Camera and Machine Vision Modules  
Battery-Powered Equipment  
Laptop, Palmtops, Notebook Computers  
Hand-Held Instruments
