Current

When

The BL9198 is designed for portable RF and

wireless applications with demanding perfor-

mance and space requirements. The BL9198

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 BL9198 also

works with low-ESR ceramic capacitors,

reducing the amount of board space

necessary for power applications, critical in

hand-held wireless devices. The BL9198

consumes less than 0.01µA in shutdown

mode and has fast turn-on time less than

50µs. The other features include ultra low

Low Dropout:210mV@300mA
