Micropower Voltage
Regulator
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)
