TECHNICAL NOTES (continued)
6. Soldering & Handling Precautions: All units are designed to be hand
soldered to pc-boards using no-clean solders (+260°C, 5 seconds max.).
Water-soluble solders can also be used, but the units must be washed
and dried using processes appropriate to the type of solder employed.
See the Mechanical Speci?cations section for pin 1 orientation and
recommended plated-through hole dimensions.

Input/Output
While 78SR regulators easily withstand a 2kV ESD discharge to any ter-
minal (using human body model), they should always be treated as ESD
sensitive devices.
7. Horizontal-Pin Models (78XXSRH-C): 78XXSRH-C switching regulators
are pin-compatible replacements for TO-220 style LM78XX linear regula-
tors that are installed with their metal tabs lying ?at on the surface of the

pc-board. However, because the surface of inductor L1 on 78XXSRH-C
models is electrically conductive, it must not be allowed to come in con-
tact with any exposed pc-board traces, other than power ground (GND).
While the 2-mil-thick (0.05mm) polyester label attached to L1 provides
some degree of electrical insulation (only if L1 sits perfectly ?at on the
pc-board), it is recommended that a 0.020” (0.5mm) clearance be main-
tained between L1 and all exposed pc-board traces.
8. Dropout Voltage: 78SR series regulators described in this data sheet
specify a minimum input voltage at which full-load accuracy and output
regulation are guaranteed (7.5V for 7803SR-C and 7805SR-C, and 15.0V
for 7812SR-C). However, these devices will stay in regulation at lower

considered to be out of regulation when its output changed by more
+/–0.005Vdc from its nominal value. All voltages were measured directly
at the regulator’s I/O pins.

? While these regulators can withstand a continuous short-circuit across their
output terminals, they will experience a signi?cant temperature rise. Extended
short-circuit operation will adversely affect the unit’s reliability.
