Note 1: The input capacitor is optional; Microchip recommends using a ceramic capacitor.
2: 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.

Note 1: These voltage references operate over the Operating Temperature Range, but with reduced performance. In any case,
the internal Junction Temperature (TJ) must not exceed the Absolute Maximum specification of +150°C.
1.1 Specification Descriptions and
Test Circuits
1.1.1 OUTPUT VOLTAGE
Output voltage is the reference voltage that is available
on the output pin (VOUT).
1.1.2 INPUT VOLTAGE
The input (operating) voltage is the range of voltage
that can be applied to the VIN pin and still have the
device produce the designated output voltage on the
VOUT pin.
1.1.3
OUTPUT VOLTAGE DRIFT (TCVOUT)
The output temperature coefficient or voltage drift is a
measure of how much the output voltage (VOUT) will
vary from its initial value with changes in ambient
temperature. The value specified in the electrical
specifications is measured and equal to:
EQUATION 1-1:
TCVOUT = -----V---O----U----T--T---A--V---N----O----M--
