Adjustable Shunt Regulators

Diodes Incorporated Adjustable Shunt Regulators are three-terminal adjustable shunt regulators with guaranteed thermal stability over the full operating range. These Diodes Incorporated regulators feature sharp turn-on characteristics, low-temperature coefficient, wide operating temperature range, and low output impedance. The adjustable shunt regulators are an ideal substitute for Zener diode in applications such as chargers, switching power supplies, and other adjustable regulators. Typical applications include voltage adapters, chargers, graphics cards, switching power supplies, and precision voltage references.
