SNVS176D – MAY 2004 – REVISED MARCH 2007

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 are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the

device is intended to be functional, but device parameter specifications may not be ensured. For ensured specifications and test

conditions, see the Electrical Characteristics.

resistance,

the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.

(4)

The human body model is a 100 pF capacitor discharged through a 1.5k

Ω resistor into each pin. The machine model is a 200pF

capacitor discharged directly into each pin.

Operating Conditions

(1)

Supply voltage, bias current product will result in aditional device power dissipation. This power may be significant. The thermal

dissipation design should take this into account.

All limits specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are

100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC)

methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
