LP3999  
Low Noise 150mA Voltage Regulator for RF/Analog  
Applications  
General Description  
Key Specifications  
n 2.5V to 6.0V Input Range  
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.  
n Accurate Output Voltage; 75mV / 2%  
>
n 60 mV Typical Dropout with 150 mA Load. Vout 2.5V  
n Virtually Zero Quiescent Current when Disabled  
n 10 µVrms output noise over 10Hz to 100kHz  
n Stable with a 1 µF Output Capacitor  
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(dis-  
able) control can be used by the system to further extend the  
battery lifetime by reducing the power consumption to virtu-  
ally zero. Should the application require a device with an  
active disable function please refer to device LP3995.  
n Guaranteed 150 mA Output Current  
n Fast Turn-on Time; 140 µs (Typ.)  
Features  
n 5 pin micro SMD Package  
n Stable with Ceramic Capacitor  
n Logic Controlled Enable  
n Fast Turn-on  
The LP3999 also features internal protection against short-  
circuit currents and over-temperature conditions.  
The LP3999 is designed to be stable with small 1.0 µF  
ceramic capacitors. The small outline of the LP3999 micro  
SMD package with the required ceramic capacitors can  
realize a system application within minimal board area.  
n Thermal-overload and short-circuit protection  
n
−40 to +125˚C junction temperature range for operation  
Applications  
Performance is specified for a −40˚C to +125˚C temperature  
range.  
n GSM Portable Phones  
n CDMA Cellular Handsets  
n Wideband CDMA Cellular Handsets  
n Bluetooth Devices  
n Portable Information Appliances  
n Handheld MP3 Devices  
The device is available in micro SMD package. For other  
package options contact your local NSC sales office.  
The device is available in fixed output voltages in the ranges  
of 1.5V to 3.3V. For availability, please contact your local  
NSC sales office.
