How to use a 555 timer to produce negative voltage How to generate Negative Voltage using 555 Timer 555 IC-Based Negative Voltage Generator   In this article, we'll show you how to build a negative voltage generator circuit using a 555 timer integrated circuit. For many electrical applications, a negative voltage is required. When a negative supply source is required for low current applications, it is unreliable. Commercially accessible choices exist, but they are either pricey or difficult to get when you need them. As a result, this circuit is technically capable of serving as a negative supply. From a positive power source, this circuit produces negative power. It is a straightforward circuit that is simple to modify to meet different needs. We are employing the 555 timer IC, one of the most well-liked and useful integrated circuits, along with a few additional parts. Components needed: 555 timer IC Capacitors (electrolytic and ceramic) Diodes Voltage regulator (optional) Resis...
