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. 7.2 Functional Block Diagram 7 XL78L05A SOP8 / XT78L05 TO92 78 XL78L05A SOP8 / XT78L05 TO92 89 XL78L05A SOP8 / XT78L05 TO92 710
