Description
IN is the input power source for the regulator. 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 about 1-10uF will ensure adequate filtering.
Ground is the negative reference for all voltages
When this input is taken low (< 0.4V), the regulator is disabled. In this state, the supply
current will drop to near zero.
Reference Bypass Pin. Connect to an external capacitor for noise reduction. A 10nF-
100nF size ceramic capacitor is recommended.
Out is the regulator output voltage used to power the load. No output capacitor is
required for stability. Output capacitance can be added to improve transient
response, noise performance and power supply ripple rejection for frequencies over
~100kHz.
