Needs validationhigh risk
AMS1117-ADJS is an adjustable LDO candidate for lower-voltage designs.
Best Alternatives to LM317LIPK
LM317LIPK is an adjustable 100mA SOT-89 regulator. Replacement choices require pinout and operating-voltage checks.
AI replacement insight
Electrical riskhigh
Vin, output type, and caps vary.
Package riskmedium
SOT-89 matches, pinout does not.
Firmware risklow
Analog regulator, no firmware.
Sourcing riskmedium
Best lead is external.
Can it be replaced directly?
Direct replacement for LM317LIPK should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with LM317LIPK.A as an external same-as lead, then validate TI package and pinout.
Main risk
Pinout and maximum input voltage are not fully proven for substitutes.
