Currently, no direct drop-in replacements have been identified. Alternatives like the TC2117-3.3VDBTR offer similar voltage but require board redesign due to different pinouts and have a lower current rating (800mA).
Best Alternatives to TLV1117LV33DCYR
TLV1117LV33DCYR is a 3.3V, 1A low-dropout (LDO) regulator in a SOT-223 package. Finding a direct pin-compatible replacement requires careful matching of its specific 4-pin pinout, current rating, and input voltage range.
AI replacement insight
Package riskhigh
Pinout mismatch is common; requires datasheet verification.
Electrical riskhigh
Candidates often have lower current or different input voltage ranges.
Firmware risklow
LDOs typically do not require firmware changes.
Can it be replaced directly?
No direct, pin-compatible replacement was found among the candidates. All options have critical differences in pinout, current, or voltage.
Best replacement path
Search for LDOs with 3.3V fixed output, >=1A current, and a 4-pin SOT-223 package, specifically verifying the pinout matches the TLV1117LV's DCY package.
Main risk
The primary risk is pinout incompatibility. Most SOT-223 LDOs are 3-pin, while the target is 4-pin, making them physically and electrically incompatible without a board redesign.
