The ZXRE250 and ZXRE252 are three terminal adjustable shunt regulators offering excellent temperature stability and output current handling capability up to 100mA. The output voltage may be set to any chosen voltage between 2.5 and 36 volts by selection of two external divider resistors. ZXRE250 has the same electrical specifications as the industry standard ‘431 except that it features a very low minimum cathode current for regulation. The typical value of 40µA makes the parts ideal for very low power applications. The devices can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance. The ZXRE250/2 is available in 2 grades with initial tolerances of 1% and 0.5% for the A and B grades respectively.
