The LP3986 is designed for portable applications withdemanding performance and space requirements. TheLP3986 performance is optimized for battery-poweredsystems to deliver ultra low noise and low quiescentcurrent. Regulator ground current increases onlyslightly in dropout, further prolonging the battery life.The LP3986 also works with low-ESR ceramiccapacitors，reducing the amount of board spacenecessary for power applications, critical in hand-heldwireless devices. The other features include ultra lowdropout voltage, high output accuracy, current limitingprotection, and high ripple rejection ratio. Available inthe 3-lead of SOT-23 packages 特点
