Frequently Asked Questions
What is the output voltage and accuracy of the REG101NA-5/250?
The REG101NA-5/250 provides a fixed 5V output voltage with ±1.5% accuracy. This means the output stays between 4.925V and 5.075V across operating conditions, making it suitable for precision analog and digital circuits requiring a stable 5V supply.
What is the dropout voltage of the REG101NA-5/250?
The REG101NA-5/250 has a typical dropout voltage of 60mV and a maximum of 130mV at full 100mA load. This ultra-low dropout characteristic allows the regulator to maintain regulation even when the input voltage is only slightly above 5V, improving efficiency in battery-powered applications.
What are the input voltage requirements for the REG101NA-5/250?
The REG101NA-5/250 requires an input voltage between 5.06V minimum and 10V maximum for normal operation, with an absolute maximum rating of 12V. Exceeding 12V may permanently damage the device. Ensure your input source stays within the 5.06V–10V operating range for reliable regulation.
What package does the REG101NA-5/250 come in and what are its typical applications?
The REG101NA-5/250 is housed in a 5-pin SOT-23 (SOT-23-5) surface-mount package, which is compact and widely used in portable electronics. Typical applications include IoT sensors, handheld instruments, wearable devices, embedded system power rails, and any design needing a small-footprint 5V LDO regulator.
Are there pin-compatible alternatives to the REG101NA-5/250?
Yes, alternatives in the SOT-23-5 package with similar 5V LDO characteristics include the Texas Instruments TLV700 series and LP2985 series. However, verify dropout voltage, quiescent current, noise specifications, and pin assignments carefully before substituting, as these parameters can vary between devices even within the same package type.
