INCHANGE Semiconductor
isc Adjustable Voltage Regulator
isc Product Specification
LM317
FEATURES
·Output Voltage Range :1.2V to 37V
·Output Current in Excess of 1.5A
·0.1% Line and Load Regulation
·Floating Opearation for High Voltages
·Complete Series of Protections:
Current Limiting,
Thermal Shutdown and SOA Control
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.
