where a catastrophic failure occurs, the output voltage may rise to
excessively high levels. If the load circuit must be protected against
all possible overvoltage situations, voltage-limiting circuitry must be
provided externally.
soldered to pc-boards, using lead-free no-clean solders (+260°C, 5
seconds max.). See the Mechanical Specifi cations section for pin 1
orientation and recommended pc-board hole dimensions.
78SR series regulators have limited built-in ESD protection; therefore
they should always be treated as ESD susceptible devices.
compatible replacements for TO-220 style LM78xx linear regulators
which are installed with their metal tabs or heat sinks laying fl at on
the surface of the pc-board. In replacement applications, 78SRH units
must be soldered to the pc-board such that the insulating body of
diode D1 lies fl at and in contact with the pc-board’s surface.
