BASIC APPLICATION CIRCUIT

*ON/OFF input must be actively terminated. Tie to V_IN if this function is not to be used.
**Minimum capacitance is shown to ensure stability (may be increased without limit). Ceramic capacitor required for
output (see APPLICATION HINTS).
***Reduces output noise (may be omitted if application is not noise critical). Use ceramic or film type with very low
leakage current (see APPLICATION HINTS).
