HT7530-1 is a 3.0V, 100mA LDO regulator from UMW in a SOT-89-3 package, notable for its high 30V maximum input voltage. Finding a replacement requires careful matching of voltage ratings and package.

AI replacement insight

Electrical riskhigh

Many alternatives have a lower maximum input voltage, which can lead to device failure.

Package riskmedium

Several functional alternatives are in different packages (e.g., SOT-23) and require a PCB redesign.

Can it be replaced directly?

Direct replacement for HT7530-1 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with UMW's HT7130-1, as it matches key specs and package. If pinout differs, consider UMW's HT7830-A if system voltage is below 12V.

Main risk

The primary risk is mismatched maximum input voltage. The target supports 30V, while many alternatives support significantly less.
