Application Notes

Low TCR Rejustors can be deployed anywhere an adjustable resistor is required. Rejustors can either be configured as dual independent resistors – such as for gain and offset adjustment, or as dividers to set a voltage ratio – for voltage regulators, for example.

As micro-power devices, the power dissipated in a Rejustor must not exceed 1mW. The resistance of Low TCR Rejustors can be adjusted up to 30% down from the as-manufactured resistance. The resistance can be increased within a finite range based on the degree to which the initial resistance was decreased.

The following application notes provide design implementation guidelines in addition to several application examples.
