微源半导体 LP3984 SOT23-5 300mA、超低噪声、小封装、超快CMOS LDO稳压器

general description

The LP3984 is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3984 performance is optimized for battery-powered systems to deliver ultra-low noise and low quiescent current. The LP3984 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.

The LP3984consumes less than 1μA in shutdown mode. 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.
