DESCRIPTION
Regulator input. If this input is within a few inches of the main supply filter, a capacitor may not be
necessary. Otherwise an input filter capacitor of 1-10µF will ensure adequate filtering.
Ground is the negative reference for all voltages
Enable input. When this input is taken low (< 0.4V), the regulator is disabled. In this state, the sup-
ply current will drop to near zero.
Reference bypass input. Connect to an external capacitor for noise reduction. A 10nF-100nF
ceramic capacitor is recommended.
Regulator output. No output capacitor is required for stability. Any type of output capacitor can be
added to improve transient response, noise performance and power supply ripple rejection for fre-
quencies over ~100kHz.
