DESCRIPTION

The BL9195 is designed for portable RF and

wireless applications with demanding perfor-

mance and space requirements. The BL9195

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 BL9195 also

works with low-ESR ceramic capacitors,

reducing

the

amount

of

board

space

necessary for power applications, critical in

tures include ultra low dropout voltage, high

output accuracy, current limiting protection,

and high ripple rejection ratio. Available in 3-

lead SOT23, SOT89 and SOT223 packages.
