Is there a pin-compatible replacement for TPS70933DBVR?

No candidate can be confirmed as pin-compatible without a direct comparison of datasheets. The SOT-23-5 package is used for many LDOs with different pin assignments for VIN, VOUT, GND, EN, and NC. Always verify the pinout before replacing.

What risks should I check before replacing TPS70933DBVR?

Before replacing, check four key areas: 1) Pinout compatibility. 2) Maximum input voltage required by your circuit. 3) Quiescent current (Iq), if your application is battery-powered. 4) The required operating temperature range.

TPS70933DBVR Alternatives, Datasheet & Cross Reference | Texas Instruments

Finding a replacement for the TPS70933DBVR LDO requires careful review. Its combination of a wide 30V input range and ultra-low 1µA quiescent current is challenging to match. Alternatives often involve trade-offs in these key parameters or have different pinouts.

AI replacement insight

Electrical riskmedium

Most alternatives have lower max input voltage or higher quiescent current.

Package riskhigh

SOT-23-5 LDO pinouts are not standardized and require datasheet verification.

Sourcing risklow

Many functional alternatives are available, though with parametric trade-offs.

Can it be replaced directly?

No confirmed drop-in replacement exists. All candidates require engineering review, especially for pinout compatibility and key electrical parameters like input voltage and quiescent current.

Best replacement path

SE8533X2-HF is the strongest candidate if the application's temperature range is within -20°C to 85°C.

Main risk

The primary risks are pinout incompatibility in the SOT-23-5 package and finding an alternative that matches both the 30V input range and 1µA quiescent current.

Recommended alternatives

A strong functional alternative with comparable input voltage and low quiescent current.
