微源半导体 LP3992-25B5F SOT23-3/SOT23-5 300mA、超低噪声、小封装、超快CMOS LDO稳压器
General Description
The LP3992-25B5F is designed for portable RF and wireless applications with demanding performance and space requirements. The LP3992 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. The LP3992 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3992 consumes less than 0.1?A in shutdown mode and has fast turn-on time less than 50?s. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. LP3992-25B5F is available in the 5-lead of SOT23-5 and TSOT23-5 packages.
