*Required if regulator is located far from power supply filter.
**C2 must be at least 100µF to maintain stability; it can be increased
without bound to maintain regulation during transients and it should be
located as close as possible to the regulator. This capacitor must be rated
over the same operating temperature range like the regulator. The ESR
of this capacitor is critical (see curve) and it should by less than 1Ω over
the expected operating temperature range.

VOUT = VREF × ( R1+R2)/R1
Note: Using 27k for R1 will automatically compensate for errors in VOUT
due to the input bias current of the Adjust Pin ( approx. 1µA)
