Negative Voltage Regulation


When the case is m (gain) equal zero and b (offset) is less than zero, the circuit is a negative voltage regulator. While a few commercial products are available, they are much fewer than positive regulators, especially switching regulators. It is possible to “fool” a positive switching regulator into generating a negative output voltage, because an AC waveform is present in the circuitry.

23.1. Introduction

When looking for a voltage regulator for your design project, the overwhelming majority of parts you will find are positive regulators. This is true whether you are looking for linear or switching regulators. I have talked about the ...
