RT9187
1A, Ultra-Low Dropout, Ultra-Fast CMOS LDO Regulator
General Description
Features
The RT9187 is a high-performance, 1A 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 RT9187 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
The RT9187 consumes less than 0.1μA in shutdown mode and has fast turn-on time less than 40μs.
