微源半导体 LP3987H-28B5F SOT23-5 600mA，超低噪声，超快CMOS LDO稳压器

General Description

TheLP3987H-28B5F is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3987H 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 LP3987H also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.The LP3987H consumes less than 0.01?A in shutdown mode and has fast turn-on time less than 20?s. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. It is available in the 5-lead of SOT23-5 packages.
