Electrical Characteristics
The following specifications apply for V
ESR
Note 1: 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 guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.
Note 2: All pins will survive an ESD impulse of
the ON/OFF input will withstand ten pulses of
capacitor.
Note 3: Exceeding the Maximum Allowable power dissipation will cause excessive die temperature, and the device will go into thermal shutdown. The θ
for the TO-220 package (still air, no additional heat sink) is 73˚C/W. The effective θ
methods.
Note 4: Exceeding the Maximum Allowable power dissipation will cause excessive die temperature, and the device will go into thermal shutdown. The θ
for the TO-263 package (still air, no additional heat sink) is 80˚C/W. The effective θ
board area that is connected (soldered) to the package tab. Using 1 ounce (1.4 mils thick) copper clad with no solder mask, an area of 0.5 square inches will reduce
θ
a solder mask, the copper clad area should be increased by at least 50% to maintain a similar θ
Note 5: Datasheet min/max specifications are guaranteed by design, test, and/or statistical analysis.
