3.3V/5V/12V Outputs High-Efﬁciency

Switching Regulators with LM78xx Pinouts

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 Speciﬁcations 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.

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 ﬂat 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 ﬂat 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

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.
