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.
