DESCRIPTION
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
dropout voltage, high output accuracy,
currentwww.DataSheet.net/ limiting protection, and high ripple
rejection ratio. Available in the 5-lead SC-70
and SOT-23 packages.
