While these regulators can withstand a continuous short-circuit across their
output terminals, they will experience a significant temperature rise. Extended
short-circuit operation will adversely affect the unit’s reliability.
of the pc-board. However, because the surface of inductor L1 on
78XXSRH models is electrically conductive, it must not be allowed to
come in contact 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
maintained 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 and 7805SR, and 15.0V
for 7812SR). 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 per-
formed 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.
