RP1202

RP1202 300mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator General Description The RP1202 is designed for portable RF and wireless applications with demanding performance and space requirements. The RP1202 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The RP1202 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RP1202 consumes less than 0.01µA in shutdown mode and has fast turn-on time less than 50µs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SOT-23 packages.
