Protection

The LP3983S is designed for portable RF and wireless

applications with demanding performance and space

requirements. The LP3983S 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

LP3983S also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for

power applications, critical in hand-held wireless

devices. The LP3983S consumes less than 0.1µA 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. It is available

in SOT23-5 packages.
