The MC78LC00 series voltage regulators are specifically designed for
use as a power source for video instruments, handheld communication
equipment, and battery powered equipment.
The MC78LC00 series features an ultra–low quiescent current of 1.1 µA
and a high accuracy output voltage. Each device contains a voltage
reference, an error amplifier, a driver transistor and resistors for setting the
output voltage. These devices are available in either SOT–89, 3 pin, or
SOT–23, 5 pin, surface mount packages.
MC78LC00 Series Features:
• Low Quiescent Current of 1.1 µA Typical
• Low Dropout Voltage (220 mV at 10 mA)
• Excellent Line Regulation (0.1%)
• High Accuracy Output Voltage (±2.5%)
• Wide Output Voltage Range (2.0 V to 6.0 V)
• Output Current for Low Power (up to 80 mA)
• Two Surface Mount Packages (SOT–89, 3 Pin, or SOT–23, 5 Pin)

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.
