LP3963/LP3966 3A Fast Ultra Low Dropout Linear Regulators

FEATURES  
DESCRIPTION  
The LP3963/LP3966 series of fast ultra low-dropout  
linear regulators operate from a +2.5V to +7.0V input  
supply. Wide range of preset output voltage options  
are available. These ultra low dropout linear  
regulators respond very quickly to step changes in  
load which makes them suitable for low voltage  
microprocessor applications. The LP3963/LP3966 are  
developed on a CMOS process which allows low  
quiescent current operation independent of output  
load current. This CMOS process also allows the  
LP3963/LP3966 to operate under extremely low  
dropout conditions.

Ultra Low Dropout Voltage  
Low Ground Pin Current  
Load Regulation of 0.06%  
15µA Quiescent Current in Shutdown Mode  
Specified Output Current of 3A DC  
Available in DDPAK/TO-263 and TO-220  
Packages  
•

•
Output Voltage Accuracy ± 1.5%  
Error Flag Indicates Output Status (LP3963)  
Sense Option Improves Load Regulation  
(LP3966)  
Dropout Voltage: Ultra low dropout voltage; typically  
80mV at 300mA load current and 800mV at 3A load  
current.

•
Minimum Output Capacitor Requirements  
Overtemperature/Overcurrent Protection  
−40°C to +125°C Junction Temperature Range  
Ground Pin Current: Typically 6mA at 3A load  
current.  
Shutdown Mode: Typically 15µA quiescent current  
when the shutdown pin is pulled low.  
APPLICATIONS

•
•
Microprocessor Power Supplies  
GTL, GTL+, BTL, and SSTL Bus Terminators  
Power Supplies for DSPs  
SCSI Terminator  
Error Flag: Error flag goes low when the output  
voltage drops 10% below nominal value (for LP3963).  
SENSE: Sense pin improves regulation at remote  
loads. (For LP3966)  
Post Regulators  
Precision Output Voltage: Multiple output voltage  
options are available ranging from 1.2V to 5.0V and  
adjustable (LP3966), with a specified accuracy of  
±1.5% at room temperature, and ±3.0% over all  
conditions (varying line, load, and temperature).  
High Efficiency Linear Regulators  
Battery Chargers  
Other Battery Powered Applications  
Typical Application Circuits  
*SD and ERROR pins must be pulled high through a 10kΩ pull-up resistor. Connect the ERROR pin to ground if this  
function is not used. See Application Hints for more information.
