CMOS LOW DROPOUT REGULATOR (LDO)

300mA ULTRA-LOW NOISE, ULTRA-FAST RESPONSE

DESCRIPTION

FEATURES

The A6303C is designed for portable applications

with demanding performance and space

requirements. The A6303C 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

A6303C also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, critical in

hand-held wireless devices. The A6303C

consumes only 0.01μA current in shutdown mode

and has fast turn-on time (Typical 50μs). The

other features include ultra low dropout voltage,

high output accuracy, current limiting protection,

and high ripple rejection ratio.
