Ordering Information
Part Number Package Option
SR087SG-G
8-Lead SOIC
Narrow Body w/ Heat Slug
-G indicates package is RoHS compliant (‘Green’)
Packing
2500/Reel
Absolute Maximum Ratings
Parameter
Value
Output voltage (VOUT)
-0.3V to 56V
Feedback voltage (VFB)
-0.3V to 6.5V
Enable voltage (VEN)
-0.3V to 6.5V
Operating junction temperature

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
referenced to device ground.
