The LP3986 is designed for portable applications with
demanding performance and space requirements. The
LP3986 performance is optimized for battery-powered
systems to deliver ultra low noise and low quiescent
current. Regulator ground current increases only
slightly in dropout, further prolonging the battery life.
The LP3986 also works with low-ESR ceramic
capacitors，reducing the amount of board space
necessary for power applications, critical in hand-held
wireless devices. The other features include ultra low
dropout voltage, high output accuracy, current limiting
protection, and high ripple rejection ratio. Available in
the 3-lead of SOT-23 packages
