MC78LC00 Series
Micropower Voltage
Regulator
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
mA.
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
mF.
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
The change in output voltage for a change in output current
at a constant temperature.
Dropout Voltage
difference between the input current (measured through the
LDO input pin) and the output current.
Line Regulation
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.
Maximum Power Dissipation
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.
Line Transient Response
Typical over and undershoot response when input voltage is
excited with a given slope.
Maximum Package Power Dissipation
The maximum total dissipation for which the regulator will
operate within its specifications.
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 actually the
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.
