BL9161G-30BARN

The BL9161G is designed for portable applications with demanding performance and space requirements. The BL9161G performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The BL9161G also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The BL9161G consumes only 0.01 μA current in shutdown mode and has fast turn-on time (Typical 50 μs). The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
