MC78BC00 Series
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.
Features
• Ultra-Low Supply Current (50 mA)
• Standby Mode (0.2 mA)
• 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%)
