Frequently Asked Questions
What is the output voltage and current rating of the TPS71523DCKRG4?
The TPS71523DCKRG4 provides a fixed 2.3V output voltage with a maximum output current of 50mA and ±4% accuracy. The nominal dropout voltage is 0.415V with a maximum of 0.75V, making it efficient for low-power embedded circuits requiring a stable 2.3V supply rail.
What is the input voltage range supported by the TPS71523DCKRG4?
The TPS71523DCKRG4 accepts an input voltage from 3V minimum to 24V maximum absolute. This broad range allows it to be powered from Li-ion batteries, USB sources, regulated 5V or 12V rails, or even higher-voltage supplies in industrial systems requiring a 2.3V output.
What package is the TPS71523DCKRG4 available in?
The TPS71523DCKRG4 is housed in a 5-pin SC-70 package (also known as SOT323), with JESD-30 code R-PDSO-G5. This is one of the smallest available surface-mount packages, making it ideal for ultra-compact designs in wearables, hearing aids, and miniaturized IoT sensor nodes.
Is the TPS71523DCKRG4 suitable for battery-powered applications?
Yes, the TPS71523DCKRG4 is well suited for battery-powered applications due to its very low dropout voltage of 0.415V nominal, fixed 2.3V output, and wide input range starting from 3V. These characteristics allow efficient operation from single Li-ion or two-cell alkaline batteries, maximizing usable energy before the regulator drops out.
