C78L00 SERIES CMOS POSITIVE VOLTAGE REGULATORS VERY LOW DROP - VERY LOW QUIESCENT .. . . LOW CURRENT CONSUMPTION (TYP. 19µA) WIDE OPERATING VOLTAGE RANGE VERY LOW DROP OUT VOLTAGE (Vi - Vo < 0.2 V, Io = 40 mA) CMOS TECHNOLOGY SO-8 DESCRIPTION The C78L00 series is a CMOS Positive Voltage Regulators. These regulators contains internal precision voltage reference, error amplifier, control transistor and output voltage setting resistor. The regulation voltage is fixed by internal circuits and the following lines of different output voltages are available. This series is suitable for battery operated items and battery back-up systems because of low current consumption and low drop out voltage.

This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate are of copper on the printed circuit board is available for the heatsinking.
