Advance Information
Micropower Voltage Regulator
The MC78BC00 voltage regulators are specifically designed to be used
with an external power transistor to deliver high current with high voltage
accuracy and low quiescent current.
The MC78BC00 series are devices suitable for constructing regulators
with ultra–low dropout voltage and output current in the range of several tens
of mA to hundreds of mA. These devices have a chip enable function, which
minimizes the standby mode current drain. Each of these devices contains a
voltage reference unit, an error amplifier, a driver transistor and feedback
resistors. These devices are available in the SOT–23, 5 pin surface mount
packages.
These devices are ideally suited for battery powered equipment, and
power sources for hand–held audio instruments, communication equipment
and domestic appliances.
MC78BC00 Series Features:
• Ultra–Low Supply Current (50 µA)
• Standby Mode (0.2 µA)
• Ultra–Low Dropout Voltage (0.1 V with External Transistor and
IO = 100 mA)
• Excellent Line Regulation (Typically 0.1%/V)
• High Accuracy Output Voltage (±2.5%)
