Low-Voltage Ref/Amplifier
SOT23-5 and SC70-5 Package

General Description
The AQ102 is a low voltage combined
reference/amplifier suited for the control loop
of low voltage power supplies. In order to
allow operation down to very low voltages,
the error amplifier output and the supply
terminal have been isolated to separate
functional pins. The nominal reference
voltage is 600 mV, the COMP output can
sink 20mA at 300mV.
Functionally, the AQ120 can be applied
similarly to industry standard TL431, except
that the reference is 600 mV and this requires a
separate Vcc connection to a supply above
2.2V. Additionally, the output of the AQ120 can
swing close to ground.
In the SC-70 package, the AQ102 is a
replacement for the MAX8515 part.
