0.6V adjustable shunt regulator

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.

The ZXRE330 is a low knee current 3.3V voltage reference. Offering tight tolerances and sharp knee characteristics, it consumes only 1µA when the 3.3V reference voltage can no longer be maintained.

The ZXSC100 series is designed for DC-DC applications where step-up voltage conversion from very low input voltages is required. These applications mainly operate from single nickel cadmium or nickel metal hydride battery cells.
