Technical Details & Description

Precision 2.5V reference for wide-temperature signal chains

Input voltage range spans 3 V to 36 V, and the part can source or sink up to 10 mA of output current. Supply current is 600 µA typical. The series topology means the output is actively regulated and can drive bypass capacitors without oscillation issues — a practical advantage over shunt references when the load current varies.

Package and marking — what to look for on receipt

6-pin TSOT-23-6 package, surface-mount only. The thin profile suits dense layouts where board height is constrained.

Lifecycle and sourcing — no LTB pressure

Active lifecycle status. ROHS3 compliant. The ADR4525ARZ-R7 (±0.04%, 4 ppm/°C, -40°C to 125°C) and ADR4525BRZ-R7 (±0.02%, 2 ppm/°C, -40°C to 125°C) are functional cross-shop candidates but do not cover the full -55°C to 125°C range.

Frequently asked questions

Can the LT6654AMPS6-2.5#TRMPBF be used as a drop-in replacement for the LT6654BMS6-2.5#TRMPBF?

The B-grade variant typically offers tighter tolerance (e.g., ±0.025%) and lower tempco (e.g., 5 ppm/°C) but shares the same pinout and package. If your design's accuracy budget allows the A-grade specs (±0.05%, 10 ppm/°C), the mechanical fit is identical. Verify the output voltage and load current requirements against the datasheet before substituting.
