AN1431T Surface-mount Adjustable Output Shunt Regulator

AN1431T, AN1431M Surface-mount Adjustable Output Shunt Regulator s Overview The AN1431T and AN1431M are high accuracy stabilized power supplies in which the output voltage can be adjusted in the range from approx. 2.5 to 36V by using the external resistor under the operating temperature. Because of its fast rise characteristics, it can be replaced with Zener.
