DESCRIPTION

inches of the main supply filter, a capacitor may not be necessary. Other-
wise, an input filter capacitor of about 1-10µF will ensure adequate filter-
ing.
The negative reference for all voltages.
Enable input. When this input is taken low (< 0.4V), the regulator is dis-
abled. In this state, the supply current will drop to near zero.
Reference Bypass Pin. Connect to an external capacitor for noise reduc-
tion. A 10nF-100nF size ceramic capacitor is recommended.
This pin sets V

response, noise performance and power supply ripple rejection for fre-
quencies over ~100kHz (see note 1).
