8.1 Overview

The LM78Lxx series of positive regulators is available in the following fixed output voltages: 5 V, 6.2 V, 8.2 V, 9 V, 12 V, and 15 V. The regulator can be configured to an adjustable output by connecting the GND pin to the center of a resistive voltage divider as shown in Figure 10. In this configuration, the fixed output voltage acts as the reference voltage across R1 allowing the output to be adjusted by changing the resistor.
