Frequently Asked Questions
What is the output voltage and current capability of the REG102NA-5/250?
The REG102NA-5/250 is a fixed 5 V output LDO regulator capable of supplying up to 250 mA of output current with a typical dropout voltage of only 150 mV, ensuring regulation is maintained even when the input supply is close to 5 V.
Why is the REG102NA-5/250 described as low-noise?
The REG102NA-5/250 features an internal noise reduction capacitor and optimized PMOS pass element design that together achieve very low output voltage noise, making it suitable for precision analog and RF applications where power supply noise degrades system performance.
What package does the REG102NA-5/250 use and what external components are needed?
The device is available in a compact 5-pin SOT-23 surface-mount package and requires only small ceramic bypass capacitors on the input and output—typically 1 µF each—for stable operation, resulting in a minimal total solution footprint on the PCB.
What is the input voltage range for the REG102NA-5/250?
The REG102NA-5/250 operates with an input voltage from 5.27 V minimum up to 10 V maximum, with an absolute maximum rating of 12 V, covering common single-cell lithium-ion and regulated DC supply scenarios in portable and benchtop electronics.
