GOFORD 431C
The 431C is a three-terminal adjustable regulator series with a guaraneed thermal stability over applicable temperature ranges. The output voltage may be set to any value between Vref (approximately 2.5 volts) and 40 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2 1C Pin Configuration TEL:0755-29961263 FAX:0755-29961466 Page 1 GOFORD TO-92 Package Information 431C Symbol A B C D E G H J Dimensions in Millimeters MIN.FEATURES
