微源半导体 LP3982-18JS5 SC-70 300mA、超低噪声、小封装、超快CMOS LDO稳压器

General Description

The The LP3982-18JS5 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3982-18JS5 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.
