0A Adjustable Positive Voltage Regulator LA317 1.
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) Features • • • • • • • Typical 1% output voltage tolerance Typical 0.
01%/V line reglation Typical 0.
2% Load Regulation Very low dropout voltage: 1.
