Pin Assignments
Absolute Maximum Ratings
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.
