This voltage detector typically features a fixed detection voltage, often in the range of 2.0V to 5.0V, specified in the part number (in this case, 2.5V may be implied). The output is generally an active-low reset signal that is asserted when the input voltage falls below the detection threshold. It uses a CMOS output. The S-80725AN-DR-T1 often comes in small surface-mount packages such as SOT-23 or similar. The specific temperature range, voltage threshold, and output configuration details can be found in the datasheet for this specific part number.
