Precision 2.5 V reference in a TSOT-23-6 — what it delivers
The LT6654BMPS6-2.5#TRMPBF from Analog Devices is a series voltage reference that holds a fixed 2.5 V output with ±0.1% initial tolerance. It runs from a 3 V to 36 V input rail and supplies up to 10 mA to the load. Noise measures 1.5 ppm p-p over 0.1 Hz to 10 Hz and 2 ppm rms over 10 Hz to 10 kHz — quiet enough to drive a high-resolution SAR ADC without an external buffer. The temperature coefficient is 20 ppm/°C, and the operating range spans -55°C to 125°C, so it fits avionics, downhole instrumentation, and satellite power-conditioning chains where the board sees wide thermal swings. The TSOT-23-6 package keeps the footprint small for dense mixed-signal layouts.
Where it lands in the precision-reference lineup
Compared to the ADR4525ARZ-R7 (0.04% tolerance, 4 ppm/°C drift, -40°C to 125°C), the LT6654BMPS6-2.5#TRMPBF trades a wider tolerance and drift for a wider temperature range and a smaller package.
