Overview
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.
