What are the primary applications for this LDO?

It is ideal for battery-powered smoke sensors, microcontrollers, and general household appliances where power efficiency and high input voltage handling are critical.

What protection features are included?

The device includes thermal shutdown, fold-back short-circuit protection, and an under-voltage lockout (UVLO) at 1.8V.

What are the key specifications?

It supports up to 200mA output current, 1% output accuracy, and operates with an input voltage range from VOUT+1V to 35V.

Are there specific design considerations for input voltage?

Yes, in-rush current can cause input voltage spikes up to 50% higher than the nominal input. Ensure the input capacitor is rated for these transients.

What should sourcing teams check before buying SE8533X2-HF?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.
