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.
