DESCRIPTION
The BL9193 is designed for portable RF and
wireless applications with demanding perfor-
mance and space requirements. The BL9193
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. The BL9193 also works with low-
ESR ceramic capacitors, reducing the
amount of board space necessary for power
applications, critical in hand-held wireless
devices. The BL9193 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, current limiting protection, and high
ripple rejection ratio. Available in the 5-lead of
SC-70, SOT-23 packages.
