SNOSBQ7C – JUNE 1999 – REVISED MAY 2013
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.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure Specific Performance limits. For ensured specifications and test
conditions, see the Electrical Characteristics.

Regulation is measured at a constant junction temperature by pulse testing with a low duty cycle. Changes in output voltage due to
heating effects must be taken into account.
