150mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator The CXCH7671 is designed for portable RF and wireless applications with demanding performance and space requirements

   产品概述 返回TOPaPi嘉泰姆

The CXCH7671 is designed for portable RF and wireless applications with demanding performance and space requirements. The CXCH7671 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The CXCH7671 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The CXCH7671 consumes less than 0.01μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70, SOT-23 and WDFN-6L 2x2 packages
