A8113E5R中文资料创瑞科技数据手册PDF规格书

DESCRIPTION

The A8113 is designed for portable RF and wireless applications with demanding performance and space requirements. The A8113 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 A8113 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The A8113 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.

The A8113 is available in SOT-25 package.
