General Description
The AS431 series ICs are three-terminal adjustable shunt regulators with guaranteed thermal stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger and other adjustable regulators.

FEATUREs
· Programmable Precise Output Voltage from 2.5V to 36V
· High Stability under Capacitive Load
· Low Temperature Deviation: 4.5mV Typical
· Low Equivalent Full-range Temperature Coefficient with 20PPM/oC Typical
· Sink Current Capacity from 1mA to 100mA
· Low Output Noise
· Wide Operating Range of -40 to 125oC

APPLICATIONs
· Charger
· Voltage Adapter
· Switching Power Supply
· Graphic Card
· Precision Voltage Reference
