Fast Turn-On  
DESCRIPTION  
The LP3981's performance is optimized for battery  
powered systems to deliver ultra low noise, extremely  
low dropout voltage and low quiescent current.  
Regulator ground current increases only slightly in  
dropout, further prolonging the battery life.  
Thermal Shutdown and Short-Circuit Current  
Limit  
KEY SPECIFICATIONS  
2.5 to 6.0V Input Range  
300mA Output  
Power supply rejection is better than 60 dB at low  
frequencies. This high power supply rejection is  
maintained down to lower input voltage levels  
common to battery operated circuits.  
60dB PSRR at 1kHz  
1μA Quiescent Current when Shut Down  
Fast Turn-On Time: 120 μs (Typ.) with CBYPASS  
= 0.01uF  
The device is ideal for mobile phone and similar  
battery powered wireless applications. It provides up  
to 300 mA, from a 2.5V to 6V input, consuming less  
than 1µA in disable mode.  
132mV Typ Dropout with 300mA Load  
35μVrms Output Noise over 10Hz to 100kHz  
The LP3981 is available in VSSOP-8 package. For  
LP3981 in WSON-6 package, contact TI sales offices.  
Performance is specified for 40°C to +125°C  
temperature range. The device available in the  
following output voltages; 2.5V, 2.7V, 2.8V, 2.83V,  
3.0V, 3.03V and 3.3V as standard. Other output  
options can be made available, please contact your  
local TI sales office.  
40 to +125°C Junction Temperature Range for  
Operation  
2.5V, 2.7V, 2.8V, 2.83V, 3.0V, 3.03V, and 3.3V  
Outputs Standard
