Product overview
Overview
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.
