Typical Applications
Note: Using 1k for R1 will ensure that the bias current error from the adjust pin will be negligible. Do not bypass R1 or
R2. This will lead to instabilities.
* Required if regulator is located far from power supply filter.
** C
OUT
must be at least 22μF 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 and the ESR is critical; see curve.

*** To assure shutdown, select Resistor R3 to ensure at least 300μA of pull-up current when S1 is open. (Assume 2V
at the ON/OFF pin.)
