... General Description The LP3981 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3981 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life ...
