*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).

Note: The actual physical placement of the package marking will vary from part to part. Package marking contains
date code and lot traceability information, and will vary considerably. Package marking does not correlate to device
type.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
