300mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator
General Description
The RT9193 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9193 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 RT9193 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in hand-held wireless
devices. The RT9193 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 SC-70-5, SOT-23-5,
TSOT-23-5, WDFN-6L 2x2 and MSOP-8 packages.
