APPLICATION INFORMATION
O UTPUT C APACITOR
To ensure the stability of the SPX1587, an
output capacitor of at least 10 μ F (ceramic or
tantalum) or 22 μ F (aluminum) is required. The
value may change based on the application
requirements of the output load or
temperature range. The value of ESR can vary
based on the type of capacitor used in the

S OLDERING M ETHODS
The SPX1587 die is attached to the heatsink
lead which exits opposite the input, output,
and ground pins.
T HERMAL C HARACTERISTICS
The SPX1587 features the internal thermal
limiting to protect the device during overload
conditions. Special care needs to be taken
during continuous load conditions such that

stability. The
the maximum junction temperature does not
recommended value for ESR is 0.5 ? or less. A
larger value of output capacitance (up to
100 μ F) can improve the load transient
response.
