RT9178 pdf datasheet (200mA, U

The RT9178 is designed for portable RF and wireless
applications with demanding performance and space
requirements.
The RT9178’ s performance is optimized for batterypowered
systems to deliver ultra low noise and low
quiescent current. A noise bypass pin is also available for
further reduction of output noise. Regulator ground current
increases only slightly in dropout, further prolonging the
battery life. The RT9178 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in hand-held wireless
devices.
The RT9178 consumes less than 0.01μA in shutdown mode
and has fast turn-on time less than 100μs. The other
features include ultra low dropout voltage, high output
accuracy, current limiting protection, and high ripple
rejection ratio. Available in the SOT-23-5 package.
