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 Specifi cations section for pin 1 orientation and
recommended plated-through hole dimensions.
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.
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 fl 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 fl 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.
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
input voltages if they are operated at less than their rated loads.
The following dropout-voltage data, derived from sample testing
performed at an ambient temperature of +25°C with resistive loads,
should be used for information purposes only. For these tests, a unit was
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.
