AME431B Adjustable Precision Shunt Regulator n General Description The AME431B series ICs are 3-terminal adjustable shunt regulator with guaranteed temperature stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impendance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger and other adjustable regulators. The reference is set to 1.24V for AME431Bxxxxx12 and 2.5V for AME431Bxxxxx25. The output voltage can be set to 1.24V to 16V for VREF=1.24V part type and 2.5 to 36V for VREF=2.5V part type with two external resistors. The AME431B precision reference is offered in two reference tolerance: 0.5% and 1.
