Frequently Asked Questions
What is the dropout voltage of the REG102NA-3.3/250?
The REG102NA-3.3/250 has a typical dropout voltage of 0.15V and a maximum dropout voltage of 0.27V at full 250mA output load. This ultra-low dropout characteristic allows the device to maintain a regulated 3.3V output even when the input voltage is only 3.57V (minimum), making it highly efficient for lithium-ion battery-powered applications near end-of-discharge.
What is the maximum output current and input voltage range of the REG102NA-3.3/250?
The REG102NA-3.3/250 provides a maximum output current of 250mA and operates from an input voltage range of 3.57V to 10V, with an absolute maximum input rating of 12V. The /250 suffix in the part number specifies the 250mA current variant, distinguishing it from lower or higher current versions in the REG102 product family.
What package does the REG102NA-3.3/250 use?
The REG102NA-3.3/250 is housed in a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5), a standard small-signal transistor outline package measuring approximately 1.6mm x 2.9mm. This tiny surface-mount package enables the regulator to be placed very close to load circuits, minimizing PCB area and reducing input/output trace inductance.
What is the expected production lifespan of the REG102NA-3.3/250?
The REG102NA-3.3/250 has a YTEOL (Years To End of Life) value of 15 years, indicating Texas Instruments plans to maintain active production of this device for approximately 15 more years. This long production lifecycle makes it suitable for designs requiring long-term component availability, such as industrial equipment with multi-decade service requirements.
