AN1432
AN1432 is Surface-mount Adjustable Output Shunt Regulator manufactured by Panasonic.
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 diode and has the wide application range.
