com RT9198/A 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.
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 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.
