Is there a pin-compatible replacement for TPRT9013-15GB?

Currently, no pin-to-pin compatible replacement has been verified. All potential alternatives are adjustable regulators that require different pin connections and external components.

What risks should I check before replacing TPRT9013-15GB?

Key risks include pinout differences between fixed and adjustable LDOs, the need for new external feedback resistors, and potential variations in performance like PSRR and transient response.

TPRT9013-15GB Alternatives, Datasheet & Cross Reference | TECH PUBLIC

TPRT9013-15GB is a 1.5V, 500mA LDO in a SOT23-5 package. While no direct pin-compatible replacements are confirmed, functional alternatives exist that require circuit modifications.

AI replacement insight

Electrical riskhigh

Adjustable vs. fixed output requires redesign and has different performance characteristics (e.g., PSRR).

Package risklow

The SOT23-5 package is a common match.

Firmware risklow

Simple LDOs typically have no firmware interaction.

Can it be replaced directly?

No direct, drop-in replacement for TPRT9013-15GB is available. All candidates require circuit modification.

Best replacement path

Use an adjustable LDO like RY6050-ADJM5R and add feedback resistors. This requires a PCB layout change.

Main risk

The primary risk is the required circuit redesign to accommodate an adjustable LDO, including different pinout and external feedback resistors.

Recommended alternatives

A functional alternative with the same package and current rating, but requires external components to set the output voltage.
