Description

The ACE5024D series are a group of positive voltage regulators manufactured by CMOS technologies

with high ripple rejection, ultra low noise, low power consumption and low dropout voltage, which can

prolong battery life in portable electronics. The ACE5024D series work with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power applications. The ACE5024D series consume

less than 0.1μA in shutdown mode and have fast turn-on time less than 50μS.The series are very suitable

for the battery-powered equipments, such as RF applications and other systems requiring a quiet voltage

source.
