Typical Applications
*Required if regulator is located far from power supply filter.
**C2 must be at least 100 μF to maintain stability. May be increased without bound to maintain regulation during
transients. Locate as close as possible to the regulator. This capacitor must be rated over the same operating
temperature range as the regulator. The equivalent series resistance (ESR) of this capacitor is critical; see curve.

Note: Using 27k for R1 will automatically compensate for errors in V
OUT
due to the input bias current of the ADJ pin
(approximately 1 μA).
