Frequently Asked Questions
What is the output voltage and accuracy of the TPS73225DCQRG4?
The TPS73225DCQRG4 provides a fixed 2.5V regulated output voltage with a tight accuracy of ±0.5%. This high precision makes it suitable for powering analog circuits, ADCs, DACs, and precision sensors where a stable and accurate 2.5V supply is critical for measurement accuracy.
What is the dropout voltage of the TPS73225DCQRG4?
The TPS73225DCQRG4 features a maximum dropout voltage of 0.15V, which means regulation is maintained with an input as low as 2.65V for a 2.5V output. This low dropout characteristic is essential in battery-powered and low-supply applications where input and output voltages are close together.
What package does the TPS73225DCQRG4 use, and is it lead-free?
The TPS73225DCQRG4 is available in a 6-pin SOT-223 package (JESD-30 code R-PDSO-G6), which provides a good thermal footprint for heat dissipation at 250mA output. It is Pb-free with a JESD-609 e4 code, confirming full RoHS compliance for use in environmentally regulated consumer and industrial products.
What are typical applications for the TPS73225DCQRG4?
Typical applications include post-regulation of 3.3V or 5V bus supplies down to 2.5V for microcontrollers, FPGAs, and precision analog circuits. It is also used in portable instruments, wireless sensors, and industrial control boards where a low-noise, low-dropout 2.5V supply with minimal external components and high output accuracy is required.
