DESCRIPTION

The

A6303A is designed for portable RF and

wireless applications with demanding performance

and space requirements. The A6303A 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 A6303A also

works with low ESR ceramic capacitors, reducing

the amount of board space necessary for power

applications, critical in hand held wireless dev ices.

The A6303A 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 A6303A is

available in SOT 23, SOT 25 and

SC70 5 P ackages.
