Overtemperature Protection
The SP619 has built-in overtemperature
protection to protect the part against dam-
age if the die temperature gets too hot. The
typical thermal cutoff is about 150篊. The
part will self recover if the temperature drops
below the thermal restart threshold of about
120篊.
Layout Considerations
The input and output decoupling capacitors
should be placed as close as possible to the
thermal performance. The input and output
traces should be as large as possible. The
and should be placed close to the output de-
coupling cap.
