Frequently Asked Questions

What output current and dropout voltage does REG102NA-A/250 support for battery-powered designs?

REG102NA-A/250 provides up to 250 mA output current with a typical dropout voltage of only 0.15 V, ensuring the LDO remains in regulation even when the input-output voltage differential is small, maximizing battery runtime in portable applications.

What input voltage range does REG102NA-A/250 accept and what is the absolute maximum rating?

REG102NA-A/250 operates from 2.2 V to 10 V input, with an absolute maximum input rating of 12 V, making it compatible with single-cell Li-ion batteries at 3.7 V up to multi-cell packs and 9 V wall adapters.

How does REG102NA-A/250 fit into compact PCB layouts for IoT nodes?

REG102NA-A/250 uses a 5-pin SOT-23 package, one of the smallest available footprints for LDO regulators, requiring only 2 external resistors to set the adjustable output between 2.5 V and 5.5 V at ±1.5% accuracy for IoT sensor modules.
