ACE621E
Ultra-Fast High PSRR 1.5A CMOS Voltage Regulator
Description
ACE621E series are a group of positive voltage regulators manufactured by CMOS technology with high
ripple rejection, ultra-fast transient response and low dropout voltage, which consume less than 1uA in
shutdown mode and can provide large output currents even when the difference of the input-output
voltage is small. Each of the ACE621E series consists of a high-precision voltage reference, an error
correction circuit, and a current limited output driver. Thus the series are very suitable for the batter-
powered equipments, wireless communication applications, industry equipments and so on.
