1 / 11 page  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 −40˚C to +125˚C 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.
