ACE500EC
Low-Dropout CMOS Voltage Regulator
Description
The ACE500EC 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 ACE500EC series work with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power applications. The ACE500EC 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 equipment’s, such as RF applications and other systems requiring a quiet voltage
source
