Preliminary
RP1215
600mA Adjustable Output Voltage CMOS LDO Regulator
General Description
The RP1215 is designed for portable RF and wireless
applicaiton with demanding performance and space
requirements. The RP1215 performance is optimized for
battery-powered systems to deliver low noise and low
quiescent current. Regulator ground current increase only
slightly in dropout, further prolonging the battery life. The
RP1215 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, ciritical in hand-held wireless devices. The
RP1215 has fast turn-on time typical 90us.The other
features include ultra low dropout voltage, current limiting
protection, and high ripple rejection ratio. Availabe in the
5-lead of SOT-23 package.
