LP3981 Datasheet - National Semiconductor

LP3981 Micropower/ 300mA Ultra Low-Dropout CMOS Voltage

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. Power supply rejection is better than 60 dB at low .
