LP3995  
Micropower 150mA CMOS Voltage Regulator with Active  
Shutdown  
General Description  
Key Specifications  
n 2.5V to 6.0V Input Range  
The LP3995 linear regulator is designed to meet the require-  
ments of portable battery-powered applications and will pro-  
vide 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 needs in which a fast turn-off is essential.  
n Accurate Output Voltage; 75mV / 2%  
n 60 mV Typical Dropout with 150 mA Load  
n Virtually Zero Quiescent Current when Disabled  
n Low Output Voltage Noise  
n Stable with a 1 µF Output Capacitor  
n Guaranteed 150 mA Output Current  
n Fast Turn-on; 30 µs (Typ.)  
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 Enable(/Disable) control  
allows the system to further extend the battery lifetime by  
reducing the power consumption to virtually zero.  
n Fast Turn-off; 175 µs (Typ.)  
Features  
The Enable(/Disable) function on the device incorporates an  
active discharge circuit on the output for faster device shut-  
down. Where the fast turn-off is not required the LP3999  
linear regulator is recommended.  
n 5 pin micro SMD Package  
n 6 pin LLP Package  
n Stable with Ceramic Capacitor  
n Logic Controlled Enable  
n Fast Turn-on  
The LP3995 also features internal protection against short-  
circuit currents and over-temperature conditions.  
The LP3995 is designed to be stable with small 1.0 µF  
ceramic capacitors. The small outline of the LP3995 micro  
SMD package with the required ceramic capacitors can  
realize a system application within minimal board area.  
n Active Disable for Fast Turn-off.  
n Thermal-overload and Short-circuit Protection  
n
−40 to +125˚C Junction Temperature Range for  
Operation  
Performance is specified for a −40˚C to +125˚C temperature  
range.  
Applications  
The device is available in micro SMD package and LLP  
package. For other package options contact your local NSC  
sales office.  
n GSM Portable Phones  
n CDMA Cellular Handsets  
n Wideband CDMA Cellular Handsets  
n Bluetooth Devices  
The device is available in fixed output voltages in the ranges  
1.5V to 3.3V. For availability, please contact your local NSC  
sales office.  
n Portable Information Appliances  
Typical Application Circuit
