Frequently Asked Questions

What is the dropout voltage of the REG101NA-3.3/250?

The REG101NA-3.3/250 features an extremely low dropout voltage of 60mV typical and 130mV maximum, allowing the output to remain regulated when the input is only slightly above 3.3V. This makes it ideal for battery-powered applications where maximizing usable battery capacity is critical.

What is the input voltage range for the REG101NA-3.3/250?

The REG101NA-3.3/250 operates with an input voltage from 3.36V minimum up to 10V maximum, with an absolute maximum rating of 12V. Exceeding 12V input may permanently damage the device, so ensure your power supply stays within the specified operating range.

What applications is the REG101NA-3.3/250 best suited for?

This LDO regulator is ideal for portable consumer electronics, IoT devices, wearables, and any 3.3V microcontroller or sensor power rail. Its ultra-low dropout voltage and compact SOT-23-5 package make it especially valuable in battery-operated systems where both board space and power efficiency are constraints.

Is the REG101NA-3.3/250 RoHS compliant?

Yes, the REG101NA-3.3/250 is fully Pb-free (lead-free) and complies with RoHS requirements, as indicated by its JESD-609 Code e4. It is suitable for use in environmentally compliant end products sold in regulated markets worldwide.
