LP3874-ADJ 0.8A Fast Ultra Low Dropout Linear Regulators  
Check for Samples: LP3874-ADJ  
1
FEATURES  
DESCRIPTION  
The LP3874-ADJ fast ultra low-dropout linear  
regulators operate from a +2.5V to +7.0V input  
supply. These ultra low dropout linear regulators  
respond very quickly to step changes in load, which  
makes them suitable for low voltage microprocessor  
applications. The LP3874-ADJ is developed on a  
CMOS process which allows low quiescent current  
operation independent of output load current. This  
CMOS process also allows the LP3874-ADJ to  
operate under extremely low dropout conditions.

Ultra Low Dropout Voltage  
Low Ground Pin Current  
Load Regulation of 0.04%  
10nA Quiescent Current in Shutdown Mode  
Specified Output Current of 0.8A DC  
Available in DDPAK/TO-263, TO-220 and SOT-  
223 Packages  
Minimum Output Capacitor Requirements  
Overtemperature/Overcurrent Protection  
40°C to +125°C Junction Temperature Range  
Dropout Voltage: Ultra low dropout voltage; typically  
24mV at 80mA load current and 240mV at 0.8A load  
current.  
APPLICATIONS  
Ground Pin Current: Typically 6mA at 0.8A load  
current.  
Microprocessor Power Supplies  
GTL, GTL+, BTL, and SSTL Bus Terminators  
Power Supplies for DSPs  
SCSI Terminator  
Shutdown Mode: Typically 10nA quiescent current  
when the shutdown pin is pulled low.  
Adjustable Output Voltage: The output voltage may  
be programmed via two external resistors.  
Post Regulators  
High Efficiency Linear Regulators  
Battery Chargers  
Other Battery Powered Applications
