DESCRIPTION

The BL9193 is designed for portable RF and

wireless applications with demanding performance

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 turnon

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.
