Specification Descriptions and
Test Circuits
The input capacitor is optional; Microchip recommends using a ceramic capacitor.
These parts are tested at both 1 µF and 10 µF to ensure proper operation over this range of load capacitors. A wider
range of load capacitor values has been characterized successfully, but is not tested in production.
These voltage references operate over the Operating Temperature Range, but with reduced performance. In any case,

The output temperature coefficient or voltage drift is a
measure of how much the output voltage (V
vary from its initial value with changes in ambient
temperature. The value specified in the electrical
specifications is measured and equal to:
