LP3986H中文资料600mA,Ultra-low Noise LDO Regulator数据手册LPSemi规格书

描述 Description

The LP3986H is designed for portable applications with demanding performance and space requirements. The LP3986H 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 LP3986H 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 and SOT-89 packages.
