Best Alternatives to SE8550X2-HF

Package: SOT-23-5Seaward ElecPMIC - Voltage Regulators - LinearOutput Voltage: 5.0 VOutput Current: 250 mAInput Voltage Range: 6.0 V to 35 VQuiescent Current: 2.5 µAOutput Accuracy: ±1%

SE8550X2-HF is a 5V, 250mA LDO in a SOT-23-5 package, notable for its high 35V input voltage tolerance. Finding a direct replacement requires careful matching of this high voltage rating, which is a key challenge.

AI replacement insight

Electrical riskhigh

Candidate max input voltage is much lower than target's 35V.

Package risklow

All candidates share the SOT-23-5 package, but pinout must be verified.

Can it be replaced directly?

Direct replacement for SE8550X2-HF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Search for LDOs in a SOT-23-5 package with a maximum input voltage of 35V or higher and at least 250mA output current.

Main risk

The primary risk is electrical overstress due to the candidates' lower maximum input voltage rating (15V-24V) compared to the target's 35V.
