General Description
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 0.1
μ
A in shutdown mode
and has fast turn-on time less than 40
μ
s. The other features
include ultra-low dropout voltage, high output accuracy,
current limiting protection, and high ripple rejection ratio.
Available in the VDFN-8L 3x3 package.
