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 charac-
teristics, it can be replaced with Zener diode and has the wide
application range.
s Features
• High precision reference voltage : 2.5V±2%
• High-temperature stability : 17ppm/˚C typ.
• Output voltage externally adjustable : 2.5 to 36V
• Fast rise
• Low input impedance : 0.2Ω (typ.)
• Low output noise voltage
