Description

The ACE575D 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 ACE575D series can deliver 250mA output current and

allow an input voltage as high as 36V. The series are very suitable for the battery-powered equipments,

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