LP3984
Micropower, 150mA Ultra Low-Dropout CMOS Voltage
Regulator in Subminiature 4-I/O micro SMD Package
General Description
The LP3984 is designed for portable and wireless applica-
tions with demanding performance and space requirements.
The LP3984’s performance is optimized for battery powered
systems to deliver extremely low dropout voltage and low
quiescent current. Regulator ground current increases only
slightly in dropout, further prolonging the battery life.
Power supply rejection is better than 60 dB at low frequen-
cies and starts to roll off at 10 kHz. High power supply
rejection is maintained down to lower input voltage levels
common to battery operated circuits.
The device is ideal for mobile phone and similar battery
powered wireless applications. It provides up to 150 mA,
from a 2.5V to 6V input, consuming less than 1.2μA in
disable mode and has fast turn-on time less than 20μs.
The LP3984 is available in micro SMD and 5 pin SOT-23
package. Performance is specified for 40C to +125C
temperature range and is available in 1.5V, 1.8V, 2.0V, and
3.1V output voltages. For other output voltage options from
1.5V to 3.5V, please contact National Semiconductor sales
office.
