How to make a Negative 6V fixed voltage DC power supply | Power supply | Using LM7906

6v fixed 1Amp negative power supply regulator.

This is a simple negative power supply circuit diagram. In this circuit, an input negative voltage of -8V to -21V can be used, with a fixed output negative voltage of -5.75V to -6.25V. This power supply can drive negative -6V, 1amp, and 15-watt devices. It can be used as a 15 watt devices. This power supply uses a voltage regulator LM7906 IC. DC to DC voltage can be converted through this circuit. This is called a stop-down negative power supply.
