2. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
DEFINITIONS
Dropout Voltage
−
The input/output voltage differential at
which the regulator output no longer maintains regulation
against further reductions in input voltage. Measured when
the output drops 100 mV below its nominal value (which is
measured at 1.0 V differential), dropout voltage is affected
by junction temperature, load current and minimum input
supply requirements.
Line Regulation
−
The change in output voltage for a
change in input voltage. The measurement is made under
conditions of low dissipation or by using pulse techniques
such that average chip temperature is not significantly
affected.
Load Regulation
−
The change in output voltage for a
change in load current at constant chip temperature.
Maximum Power Dissipation
−
The maximum total device
dissipation for which the regulator will operate within
specifications.
Quiescent Bias Current
−
Current which is used to operate
the regulator chip and is not delivered to the load.

APPLICATIONS INFORMATION
Introduction
The MC78FC00 micropower voltage regulators are
specifically designed with internal current limiting and low
quiescent current making them ideal for battery powered
applications. An input bypass capacitor is recommended if
the regulator is located an appreciable distance (≥ 4 inches)
from the input voltage source. These regulators require
0.1
mF
capacitance between the output terminal and ground
for stability. Most types of aluminum, tantalum or multilayer
ceramic will perform adequately. Solid tantalums or other
appropriate capacitors are recommended for operation
below 25°C. The bypass capacitors should be mounted with
the shortest possible leads or track lengths directly across the
regulator input and output terminals.
With economical electrolytic capacitors, cold temperature
operation can pose a serious stability problem. As the
electrolyte freezes, around
−30°C,
the capacitance will
decrease and the equivalent series resistance (ESR) will
increase drastically, causing the circuit to oscillate. Quality
electrolytic capacitors with extended temperature ranges of
−40°
to +85°C are readily available. Solid tantalum
capacitors may be the better choice if small size is a
requirement. However, a maximum ESR limit of 3.0
W
must
be observed over temperature to maintain stability.
Figure 6 is a typical circuit application. Figure 7 is a
current boost circuit which can deliver more than 600 mA.
The circuit has no current limiting and the external transistor
must be rated for the expected power dissipation.
