产品简介

The BL9193 is designed for portable RF and wireless applications with demanding performance and space re The BL9193 performance is optimized for battery-powered systems to deliver ultra low noise and low 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 BL9193 also works with low- ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The BL9193 consumes less than 0.01μA in shutdown mode and has fast turnon 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 packages.
