MB431U

MB431U Adjustable Precision Shunt Regulator Description The MB431U is a 3-terminal adjustable shunt regulator with guaranteed temperature stability over the entire temperature range of operation. The output voltage may be set at any level greater than 2.5V (VREF) up to 18V merely by selecting two external resistors that act as a voltage divided network. Due to the sharp turn-on characteristics this device is an excellent replacement for many zener diode applications Features „ Average temperature coefficient 50 ppm/°C „ Temperature compensated for operation over the full temperature range „ Programmable output voltage „ Fast turn-on response low output noise CBC Microelectronics http://www.cbcv.net Pin Configuration SOP8 Figure 1: Package Types of MB431U CBC Microelectronics Co., LTD.
