AQ102
Low-Voltage Ref/Amplifier
SOT23-5 SC70-5 Package
Product Specification Revision 2005
General Description
AQ102 voltage combined reference/amplifier suited control loop voltage power supplies. order allow operation down very voltages, error amplifier output supply terminal have been isolated separate functional pins. nominal reference voltage COMP output sink 20mA 300mV. Functionally, AQ120 applied similarly industry standard TL431, except that reference this requires separate connection supply above 2.2V. Additionally, output AQ120 swing close ground. SC-70 package, AQ102 replacement MAX8515 part.
Applications Power supply control loop Power supply supervisory functions Features input voltage reference 600mV high accuracy voltage reference voltage reference High PSRR line regulation current consumption Offered ultra small SC70-5 package Zero offset error amplifier Open collector output RoHS compliant
