Description

The ACE5019A series are a group of positive voltage regulators manufactured by CMOS technologies

with low power consumption and low dropout voltage, which provide large output currents even when the

difference of the input-output voltage is small. The ACE5019A series can deliver 300mA output current

and allow an input voltage as high as 18V. The series are very suitable for the battery-powered

equipments, such as RF applications and other systems requiring a quiet voltage source.
