BL8077  
0.8uA Low Power Consumption Regulator with Enable  
DESCRIPTION  
FEATURES  
Maximum output current:300mA  
Low power consumption: 0.8uA (Typ.)  
Stand-by current: less than 0.1uA  
Operating input voltage:1.8V~5.5V  
Low dropout voltage:  
150mV @100mA @VOUT=3.3V (Typ.)  
Low temperature coefficient: ±100ppm/C  
Build-in chip enable and discharge circuit  
Built-in output current limit circuit  
The BL8077 is a group of positive voltage output,  
low power consumption, low dropout voltage  
regulator. The very low power consumption of  
BL8077 (0.8uA, Typ) can greatly improve natural  
life of batteries. The BL8077 includes high  
accuracy voltage reference, error amplifier and  
output driver module with discharge capability.  
And it also provides foldback short-circuit  
protection, thermal protection and output  
current limit function.  
APPLICATIONS  
The BL8077 can provide output value of fixed  
version as 1.2V, 1.8V, 2.5V, 2.8V, 3V, and 3.3V. It  
also can be customized on command.  
Mobile phones  
Battery powered equipment  
Cordless phones, wireless communication  
equipment  
Cameras, video recorders  
Portable AV equipment  
PDAs  
BL8077 is available in SOT23-5 and DFN1x1-4  
which are lead free.
