LP3995  
Micropower 150mA CMOS Voltage Regulator with Active  
Shutdown  
General Description  
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 de-  
vices, this device will also be used to meet more general  
circuit needs in which a fast turn-off is essential.  
Key Specifications  
2.5V to 6.0V Input Range  
■

■
■
■
■
■
■
Accurate Output Voltage; ±75mV / 2%  
60 mV Typical Dropout with 150 mA Load  
Virtually Zero Quiescent Current when Disabled  
Low Output Voltage Noise  
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 Enable(/Disable) control al-  
lows the system to further extend the battery lifetime by  
reducing the power consumption to virtually zero.  
Guaranteed 150 mA Output Current  
Fast Turn-on; 30 µs (Typ.)  
Fast Turn-off; 175 µs (Typ.)  
■
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.  
Features  
5 pin micro SMD Package

■
■
■
■
■
6 pin LLP Package  
The LP3995 also features internal protection against short-  
circuit currents and over-temperature conditions.  
Stable with Ceramic Capacitor  
Logic Controlled Enable  
The LP3995 is designed to be stable with small 1.0 µF ce-  
ramic capacitors. The small outline of the LP3995 micro SMD  
package with the required ceramic capacitors can realize a  
system application within minimal board area.  
Fast Turn-on  
Active Disable for Fast Turn-off.  
Thermal-overload and Short-circuit Protection  
Performance is specified for a −40°C to +125°C temperature  
range.  
−40 to +125°C Junction Temperature Range for Operation  
■
The device is available in micro SMD package and LLP pack-  
age. For other package options contact your local NSC sales  
office.  
Applications  
GSM Portable Phones

CDMA Cellular Handsets  
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.
