The EA9104 is designed for portable RF and wireless applications with demanding performance and space requirements.

The EA9104 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.

The EA9104 consumes less than 0.1uA in shutdown mode.

Regulator ground current increases only slightly in dropout, further prolonging the battery life.

The EA9104 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.

The EA9104 consumes less than 0.01uA in shutdown mode and has fast turn-on time less than 50us.

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 SOT23-5 and 6-lead of SOT23-6 packages.
