DESCRIPTION  
KEY FEATURES  
■ Three-Terminal Adjustable Or Fixed  
TheLX8385/85A/85Bseriesdevicesare  
pin-compatible with earlier 3-terminal  
The LX8385/8385A/8385B series ICs are  
positive regulators designed to provide  
3A output current. Each regulator yields  
higher efficiency than currently available  
devices with all internal circuitry designed  
to operate down to a 1V input-to-output-  
differential. In these products, the drop-  
out voltage is fully specified as a function  
of load current. The LX8385's dropout is  
guaranteed at a maximum of 1.5V at maxi-  
mum output current, decreasing at lower  
load currents. The LX8385A/85B have a  
maximum dropout voltage of 1.3V.  
Output Voltage  
■ Guaranteed 1% Voltage Reference  
Accuracy Over Line, Load And  
Temperature (LX8385B)  
regulators, such as 117 series products.  
While a 10µF output capacitor is required  
on both input and output of these new  
devices, this is generally included in most  
regulator designs.  
The quiescent current of the LX8385/  
85A/85B series products flows into the  
load, increasing efficiency. This feature  
contrasts with PNP regulator designs,  
where up to 10% of the output current is  
wasted as quiescent current.  
■ Guaranteed < 1.5V Headroom At 3A  
(LX8385)  
■ Guaranteed < 1.3V Headroom At 3A  
(LX8385A/8385B)  
■ Output Current Of 3A Minimum  
p 0.015% Line Regulation  
p 0.1% Load Regulation  
The LX8385B offers a tighter voltage  
reference tolerance: ±1.0% over line, load  
and temperature, with 0.8% initial accu-  
racy. The LX8385/85A have 1.0% initial  
accuracy, with 2% over line, load and tem-  
perature.  
The LX8385-xxI is rated for -25°C to  
+125°Capplications, andtheLX8385-xxC  
/8385B-xxC is rated for 0°C to +125°C  
applications.
