DESCRIPTION
The BL9195 is designed for portable RF and wireless applications with demanding performance and space requirements.
The BL9195 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 BL9195 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in 3-lead SOT23 and SOT89 packages.
