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.

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 300

μA of pull-up current when S1 is open. (Assume 2V

at the ON/OFF pin.)
