RP1222 300mA Adjustable Output Voltage CMOS LDO Regulator General Description The RP1222 is designed for portable RF and wireless applicaiton with demanding performance and space requirements. The RP1222 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 RP1222 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, ciritical in hand-held wireless devices. The RP1222 has soft start time typical 1300µs.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.
