Voltage Reference vs. Voltage Regulator

It's important to distinguish voltage references from voltage regulators. While both provide stable output voltages, voltage references are optimized for accuracy and stability rather than power delivery. They serve as precision benchmarks for measurement and control circuits, whereas voltage regulators focus on supplying stable power to loads with varying current demands.
