Notes:

1. Junction to ambient thermal resistance for the S.O. (M) package is 160°C/W.

2 May exceed input supply voltage.

3. When used in dual-supply systems where the output terminal sees loads returned to a negative supply, the output voltage

should be diode-clamped to ground.

Electrical Characteristics

The • denotes that the limits apply at temperature extremes.
