Frequently Asked Questions
What is the output voltage and accuracy of the TPS71725DCKT?
The TPS71725DCKT provides a fixed 2.5V output voltage with ±3% accuracy. This ensures stable and precise voltage regulation suitable for sensitive analog and digital circuits requiring a reliable 2.5V supply rail.
What is the dropout voltage of the TPS71725DCKT and why does it matter?
The TPS71725DCKT has a typical dropout voltage of 0.17V and a maximum of 0.3V at full 150mA load. Low dropout voltage means the regulator can maintain regulation even when the input voltage is only slightly higher than the 2.5V output, extending battery life in portable applications.
What package does the TPS71725DCKT use and what are its dimensions?
The TPS71725DCKT comes in a 5-pin SC-70 package (also referred to as SOT-23-5). This is an ultra-compact surface-mount package ideal for space-constrained PCB layouts in handheld and wearable devices.
Can the TPS71725DCKT be used with lithium-ion batteries?
Yes, the TPS71725DCKT supports an input voltage range of 2.5V to 6.5V, which is compatible with single-cell lithium-ion batteries (nominal 3.7V, fully charged ~4.2V). It can efficiently regulate down to 2.5V output throughout most of the battery's discharge cycle.
What are common alternatives or substitutes for the TPS71725DCKT?
Common alternatives include the TPS71733DCKT (3.3V fixed output variant from TI), MCP1700 series from Microchip, and XC6206 series from Torex. When substituting, verify the output voltage, dropout voltage, maximum current rating, and package footprint compatibility for your design.
