0A Adustable Positive
Voltage Regulator
General Description
• The LA317 is an adjustable 3-terminal positive
voltage regulator with a very low dropout of 1.
2V at 1A output current.
Using 2 external resistors, the LA317 can provide an adjustable output
voltage down to 1.
25V.
• The LA317 is available in standard SOT-223, D-PACK, TO-220 and D2-PACK packages.
TO-220 D2-PACK (TO-263) SOT-223 D-PACK (TO-252)
