LP3874-ADJ  
0.8A Fast Ultra Low Dropout Linear Regulators  
General Description  
Features  
n Ultra low dropout voltage  
n Low ground pin current  
The LP3874-ADJ fast ultra low-dropout linear regulators op-  
erate 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 ex-  
tremely low dropout conditions.  
n Load regulation of 0.04%  
n 10nA quiescent current in shutdown mode  
n Guaranteed output current of 0.8A DC  
n Available in TO-263, TO-220 and SOT-223 packages  
n Minimum output capacitor requirements  
n Overtemperature/overcurrent protection  
n −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.  
n Microprocessor power supplies  
n GTL, GTL+, BTL, and SSTL bus terminators  
n Power supplies for DSPs  
n 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.  
n Post regulators  
n High efficiency linear regulators  
n Battery chargers  
n Other battery powered applications  
Typical Application Circuit
