LP3995 Micropower 150mA CMOS Voltage Regulator with Active Shutdown  
Check for Samples: LP3995

FEATURES  
DESCRIPTION  
The LP3995 linear regulator is designed to meet the  
requirements of portable 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 needs in which a  
fast turn-off is essential.

Stable With Ceramic Capacitor  
Logic Controlled Enable  
Fast Turn-On  
Active Disable for Fast Turn-Off  
Thermal-overload and Short-Circuit Protection  
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.  
−40 to +125°C Junction Temperature Range for  
Operation  
APPLICATIONS  
The Enable(/Disable) function on the device  
incorporates an active discharge circuit on the output  
for faster device shutdown. Where the fast turn-off is  
not required the LP3999 linear regulator is  
recommended.

Input Range: 2.5V to 6.0V  
The LP3995 is designed to be stable with small 1.0  
µF ceramic capacitors. The small outline of the  
LP3995 DSBGA package with the required ceramic  
capacitors can realize a system application within  
minimal board area.  
Accurate Output Voltage: ±75mV / 2%  
Typical Dropout with 150 mA Load: 60mV  
Virtually Zero Quiescent Current when  
Disabled  
Performance is specified for a −40°C to +125°C  
temperature range.

Low Output Voltage Noise  
Stable with an Output Capacitor of 1µF  
Output Current: 150mA  
The device is available in DSBGA package and  
WSON package. For other package options contact  
your local TI sales office.  
Fast Turn-on: 30µs (Typ.)  
Fast Turn-off: 175µs (Typ.)  
The device is available in fixed output voltages in the  
ranges 1.5V to 3.3V. For availability, please contact  
your local TI sales office.
