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.
