Is there a pin-compatible replacement for TPS79301DBVR?

Currently, no replacement has been verified as pin-compatible. The RT9065GE from Richtek is available in the same SOT-23-6 package and should be reviewed by an engineer to confirm pin-for-pin compatibility and electrical suitability.

What risks should I check before replacing TPS79301DBVR?

Before replacing, you must verify the package and pinout to ensure mechanical and electrical connection compatibility. Also, compare key electrical parameters like dropout voltage, quiescent current, and especially Power Supply Rejection Ratio (PSRR) and output noise, as the TPS79301DBVR is designed for noise-sensitive applications.

TPS79301DBVR Alternatives, Datasheet & Cross Reference | Texas Instruments

The Texas Instruments TPS79301DBVR is a 200mA low-dropout regulator known for its high PSRR and low noise in a SOT-23-6 package. Finding a substitute requires careful matching of not only the package and pinout but also these critical noise performance characteristics.

AI replacement insight

Package riskhigh

Several candidates have different packages, requiring a board redesign.

Electrical riskmedium

Candidates may have different PSRR and noise characteristics critical for the target's applications.

Can it be replaced directly?

No verified direct or pin-to-pin replacement has been identified. The RT9065GE is in the same package and warrants review.

Best replacement path

Review RT9065GE for pinout and electrical compatibility. If not compatible, TPS7A2501DRVR is a functional alternative requiring a PCB redesign.

Main risk

The primary risks are pinout incompatibility and degraded noise/PSRR performance, which is a key feature of the target part.

Recommended alternatives

Functional alternative with higher current, but in a different package requiring board redesign.
