300mA, Low Noise, Ultra-Fast CMOS LDO Regulator
General Description
The RT9198/A is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9198/A 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 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 0.01
μ
A in
shutdown mode and has fast turn-on time less than 50
μ
s.
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,
SC-70-5, SC-82 and WDFN-6L 2x2 packages, the RT9198/
A also offers a range from 1.5V to 5.0V with 0.1V
per
step.
