1 / 8 page  Preliminary Datasheet LP3982 LP3982 – Ver. 1.0 Datasheet Dec.-2006 Page 1 of 8 300mA,Ultra-low noise, Small Package Ultra-Fast CMOS LDO Regulator General Description The The LP3982 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3982 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 LP3982 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3982 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 SC-70 packages.
