600mA,Ultra-low noise, Ultra-Fast CMOS LDO Regulator

General Description

The LP3987H 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 0.01µA in shutdown mode and has fast turn-on time less than 20µs. 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.
