Is there a pin-compatible replacement for LM27762DSSR?

Yes, the LM27762DSST is a pin-to-pin compatible replacement. It shares the same WSON-12 package, pinout, and all electrical specifications, differing only in tape and reel size.

What risks should I check before replacing LM27762DSSR?

The main risk is functional mismatch. Many regulators provide only a single positive output, while the LM27762DSSR provides both positive and negative rails. Always verify the replacement offers dual outputs if your application requires it.

LM27762DSSR Alternatives, Datasheet & Cross Reference | Texas Instruments

The LM27762DSSR from Texas Instruments is a versatile charge pump regulator providing both positive and negative outputs. Finding a direct replacement requires matching its unique dual-output function, package, and key electrical ratings.

AI replacement insight

Electrical riskhigh

High risk if using any part other than the packaging variant due to functional differences (dual vs. single output).

Package riskhigh

High risk for non-variant parts as they use different packages and pinouts, requiring a board redesign.

Sourcing risklow

The target and its direct replacement are both listed as Active.

Can it be replaced directly?

Yes, the LM27762DSST is a direct, pin-compatible replacement for the LM27762DSSR, differing only in reel size.

Best replacement path

Use the packaging variant LM27762DSST for a direct, no-risk replacement.

Main risk

Functional mismatch is the primary risk; most alternatives are single-output LDOs and cannot replace the dual-output charge pump function.

Recommended alternatives

A pin-compatible packaging variant of the target part with identical electrical and physical specifications.
