DESCRIPTION  
KEY SPECIFICATIONS  
The LP3999 regulator is designed to meet the  
requirements of portable wireless battery-powered  
applications and will provide an accurate output  
voltage with low noise and low quiescent current.  
Ideally suited for powering RF/Analog devices this  
device will also be used to meet more general circuit  
requirements.

•
2.5V to 6.0V Input Range  
Accurate Output Voltage; ±75mV / 2%  
60 mV Typical Dropout with 150 mA Load. Vout  
> 2.5V  
•
Virtually Zero Quiescent Current when  
Disabled  
For battery powered applications the low dropout and  
low ground current provided by the device allows the  
lifetime of the battery to be maximized.The inclusion  
of an Enable(disable) control can be used by the  
system to further extend the battery lifetime by  
reducing the power consumption to virtually zero.  
Should the application require a device with an active  
disable function please refer to device LP3995.

10 μVrms Output Noise Over 10Hz to 100kHz  
Stable with a 1 μF Output Capacitor  
Ensured 150 mA Output Current  
Fast Turn-on Time; 140 μs (Typ.)  
The LP3999 also features internal protection against  
short-circuit
