isc Adjustable Voltage
Regulator
FEATURES ·Output Voltage Range :1.2V to 37V ·Output Current In Excess of 1.5A ·0.1% Line and Load Regulation ·Floating Operation for High Voltage ·100% avalanche tested ·Minimum Lot-to-Lot variations for robust device
performance and reliable operation
DESCRIPTION ·They are designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range. ·The nominal output voltage is selected by means of only a resistive divider,making the device exceptionally easy to use and eliminating the stocking of many fixed
regulators.
