The MC78FC00 series voltage regulators are specifically designed for
use as a power source for video instruments, handheld communication
equipment, and battery powered equipment.
The MC78FC00 series voltage regulator ICs feature a high accuracy
output voltage and ultra–low quiescent current. Each device contains a
voltage reference unit, an error amplifier, a driver transistor, and resistors for
setting output voltage, and a current limit circuit. These devices are available
in SOT–89 surface mount packages, and allow construction of an efficient,
constant voltage power supply circuit.
MC78FC00 Series Features:
• Ultra–Low Quiescent Current of 1.1 µA Typical
• Ultra–Low Dropout Voltage (100 mV at 10 mA)
• Large Output Current (up to 120 mA)
• Excellent Line Regulation (0.1%)
• Wide Operating Voltage Range (2.0 V to 10 V)
• High Accuracy Output Voltage (±2.5%)
• Wide Output Voltage Range (2.0 V to 6.0 V)
• Surface Mount Package (SOT–89)

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

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.
