DESCRIPTION

The LR9193 is designed for portable RF and

wireless

applications

with

demanding

performance and space requirements. The

LR9193 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 LR9193 also works with low-

ESR ceramic capacitors, reducing the

amount of board space necessary for power

applications, critical in hand-held

wireless

devices. The LR9193 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.

APPLICATIONS



Cellular and Smart Phones

Battery-Powered Equipment

Laptop, Palmtops,Notebook Computers

Hand-Held Instruments
