RT9198/A

300mA, Low Noise, Ultra-Fast CMOS LDO Regulator

General Description

Ordering Information

RT9198/A-

The RT9198/A is designed for portable RF and wireless

applications with demanding performance and space

requirements. The RT9198/Aperformance 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 RT9198/A also works with low-ESR ceramic

capacitors, reducing the amount of board space necessary

for power applications, critical in hand-held wireless

devices. The RT9198/A consumes less than 0.01uA in

shutdown mode and has fast turn-on time less than 50us.

The other features include ultra low dropout voltage, high

output accuracy, current limiting protection, and high ripple

rejection ratio. Available in the SOT-23-3, SOT-23-5,

TSOT-23-3, TSOT-23-5, SC-70-5, SC-82, MSOP-8 and

WDFN-6L 2x2 packages, the RT9198/Aalso offers a range

from 1.5V to 5.0V with 0.1V per step.
