RT9187A
300mA, Ultra-Low Dropout, Ultra-Fast CMOS LDO Regulator
General Description
The RT9187A is a high-performance, 300mA LDO regulator, offering extremely high PSRR and ultra-low dropout. Ideal for portable RF and wireless applications with demanding performance and space requirements.
A noise reduction pin is also available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The RT9187A also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
The RT9187A consumes less than 0.1μA in shutdown mode and has fast turn-on time less than 100μs.
