Most commonly used to provide a stable reference for more complex active regulators (e.g., driving the base of a pass transistor).

Designing an effective power Zener regulator requires balancing current limits to ensure the diode remains in its "on" state without exceeding its thermal capacity. 2.1 Resistor Selection The series resistor RScap R sub cap S Power Zener Diodes as Voltage Regulators - Circ...
