ACE5227C
600mA Fast Response Linear Regulator
Description
ACE5227C series is a group of positive voltage output, low power consumption, low dropout voltage
regulator.
ACE5227C can provide output value adjustable from0.8V to 5.0V.
ACE5227C includes high accuracy voltage reference, error amplifier, and current limit circuit and output
driver module with discharge capability.
ACE5227C has excellent load and line transient response and good temperature characteristics, which
can assure the stability of chip and power system. It uses trimming technique to guarantee output voltage
accuracy within ±2%. And it also provides fold back short-circuit protection, thermal protection and output
current limit function.
ACE5227C is available in SOT23-5 and SC70-5 packages which are lead free.
