† Notice: Boldface limits apply at temperature extremes.

†† Notice: If Military/Aerospace specified devices are required, contact your local representative/distributor for

availability and specifications.

Note 1: The thermal resistance of the 8-pin DIP package is 105°C/W junction-to-ambient when soldered directly to

a PC board. Junction-to-ambient thermal resistance for the SOIC (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.
