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

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.
