The MC78LC00 series of fixed output low dropout linear regulators
are designed for handheld communication equipment and portable
battery powered applications which require low quiescent current. The
MC78LC00 series features an ultra−low quiescent current of 1.1 A.
Each device contains a voltage reference unit, an error amplifier, a
PMOS power transistor, and resistors for setting output voltage.
The MC78LC00 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 F. The
device is housed in the micro−miniature Thin SOT23−5 surface mount
package and SOT−89, 3 pin. Standard voltage versions are 1.5, 1.8,
2.5, 2.7, 2.8, 3.0, 3.3, 4.0, and 5.0 V. Other voltages are available in
100 mV steps.

DEFINITIONS
Load Regulation
actually the difference between the input current (measured
through the LDO input pin) and the output current.
The change in output voltage for a change in output
current at a constant temperature.
Line Regulation
Dropout Voltage
The change in output voltage for a change in input voltage.
The measurement is made under conditions of low
dissipation or by using pulse technique such that the average
chip temperature is not significantly affected.
The input/output differential at which the regulator output
no longer maintains regulation against further reductions in
input voltage. Measured when the output drops 3% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Line Transient Response
Maximum Power Dissipation
Typical over and undershoot response when input voltage
is excited with a given slope.
The maximum total dissipation for which the regulator
will operate within its specifications.
Maximum Package Power Dissipation
The maximum power package dissipation is the power
dissipation level at which the junction temperature reaches
its maximum operating value, i.e. 125°C. Depending on the
ambient power dissipation and thus the maximum available
output current.
Quiescent Current
The quiescent current is the current which flows through
the ground when the LDO operates without a load on its
output: internal IC operation, bias, etc. When the LDO
becomes loaded, this term is called the Ground current. It is

MC78LC00 Series
APPLICATIONS INFORMATION
Thermal
A typical application circuit for the MC78LC00 series is
shown in Figure 20.
As power across the MC78LC00 increases, it might
become necessary to provide some thermal relief. The
maximum power dissipation supported by the device is
dependent upon board design and layout. Mounting pad
configuration on the PCB, the board material, and also the
ambient temperature effect the rate of temperature rise for
the part. This is stating that when the MC78LC00 has good
thermal conductivity through the PCB, the junction
temperature will be relatively low with high power
dissipation applications.
The maximum dissipation the package can handle is
given by:
Input Decoupling (C1)
A 0.1 F capacitor either ceramic or tantalum is
recommended and should be connected close to the
MC78LC00 package. Higher values and lower ESR will
improve the overall line transient response.
Output Decoupling (C2)
The MC78LC00 is a stable component and does not
require any specific Equivalent Series Resistance (ESR) or
a minimum output current. Capacitors exhibiting ESRs
ranging from a few mΩ up to 3.0 can thus safely be used.
The minimum decoupling value is 0.1 F and can be
augmented to fulfill stringent load transient requirements.
The regulator accepts ceramic chip capacitors as well as
tantalum devices. Larger values improve noise rejection and
load regulation transient response.
PD If junction temperature is not allowed above the
maximum 125°C, then the MC78LC00NTR can dissipate
up to 357 mW @ 25°C.
The power dissipated by the MC78LC00NTR can be
calculated from the following equation:
Hints
Please be sure the Vin and Gnd lines are sufficiently wide.
When the impedance of these lines is high, there is a chance
to pick up noise or cause the regulator to malfunction.
Set external components, especially the output capacitor,
as close as possible to the circuit, and make leads as short as
possible.

If an 80 mA output current is needed then the ground
current from the data sheet is 1.1 A. For an
MC78LC30NTR (3.0 V), the maximum input voltage will
then be 7.4 V.
