The output voltage may be set to any value between VREF (approximately 2.495v) and 36v with two external resistors. It provides very wide applications, including shunt regulator, series regulator, switching regulator, voltage reference and others. Package Dimensions Millimeter Millimeter REF. Min. Max. REF. Min.
