ACE529C 1A Low Dropout Voltage Linear Regulator Description ACE529C series are a group of positive voltage output, high precise, and low power consumption voltage regulator. Voltages are selectable in 100mV steps within a range of 1.2V to 5.0V. It also can be customized on command. ACE529C series have excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within ±2%. ACE529C series are available in SOT-23-5 package, which is lead (Pb)- free.
