Product details
Overview
LT6654BMPS6-5#TRPBF from Analog Devices is a precision 5V voltage reference IC with ±0.10% initial accuracy, 20ppm/°C max temperature drift, and ±10mA output drive capability in a 6-lead TSOT-23 package. It operates from –55°C to 125°C, supports input voltages up to 36V, and delivers 1.6ppmP-P low-frequency noise (0.1Hz–10Hz), making it suitable for high-resolution data acquisition systems requiring stable excitation or ADC reference in harsh environments.
For engineers reviewing the LT6654BMPS6-5#TRPBF datasheet, LT6654BMPS6-5#TRPBF pinout, LT6654BMPS6-5#TRPBF application, or LT6654BMPS6-5#TRPBF equivalent, this page provides verified specifications, thermal stability data across the full –55°C to 125°C range, load regulation performance at ±10mA, dropout behavior under sourcing/sinking conditions, and validated automotive-grade alternatives for mission-critical designs.
Technical Context
The LT6654BMPS6-5#TRPBF implements a curvature-compensated bandgap core with buffered output stage, enabling bidirectional ±10mA current delivery while maintaining precise load regulation (≤8ppm/mA sourcing, ≤20ppm/mA sinking). Its architecture supports operation as both positive and negative voltage references via sink capability.
Designed for extended temperature reliability, it features low thermal hysteresis (50ppm over –55°C to 125°C in TSOT-23), long-term drift of 60ppm/√kHr, and AEC-Q100 qualification for automotive use. The 6-lead TSOT-23 package includes two dedicated GND pins (Pins 2 and 3) for star-grounding and two VOUT pins (Pins 5 and 6) tied together for optimal load regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.10% (±5mV) at 25°C - ensures accurate scaling for 16-bit+ SAR ADCs without calibration. |
| Temp Coefficient | 20ppm/°C max (B-grade) - limits full-range error to ±2.5mV over –55°C to 125°C. |
| Output Noise | 1.6ppmP-P (0.1Hz–10Hz) - contributes <8µVP-P noise to 5V reference, critical for sub-LSB stability. |
| Load Regulation | 8ppm/mA max sourcing, 20ppm/mA max sinking - maintains <±0.04mV shift per mA load change. |
| Dropout Voltage | 100mV max at ±10mA - allows operation with VIN as low as 5.1V, reducing power loss in low-headroom supplies. |
| Supply Range | Up to 36V input - enables direct connection to unregulated industrial rails without external regulators. |
| Operating Temp | –55°C to 125°C (MP-grade) - qualified for downhole, engine bay, and aerospace applications. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (1mm height), RoHS-compliant, tape-and-reel (#TRPBF).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (DNC) | Do Not Connect | Internally connected; external connection risks leakage-induced error or instability. |
| Pin 2 (GND) | Primary Device Ground | Star-ground connection point for load and PCB ground plane; lowest impedance return path. |
| Pin 3 (GND) | Internal Function Ground | Must be tied to Pin 2 near device; separates internal bias currents from main ground path. |
| Pin 4 (VIN) | Power Supply Input | Bypass with ≥0.1µF capacitor to Pin 2; supports 5.1V–36V operation with 100mV dropout. |
| Pin 5 (VOUT) | Main Output Terminal | Requires ≥1µF output capacitor; connects to Pin 6 for improved load regulation and PSRR. |
| Pin 6 (VOUT) | Secondary Output Terminal | Must be tied directly to Pin 5; reduces output impedance and improves current-sharing symmetry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050QPWRQ1 | 0.05% initial accuracy, 3ppm/°C drift, 10ppmP-P noise, 10mA drive, SOIC-8 package | Lower drift/noise but limited to –40°C to 125°C; no MP-grade –55°C rating | Select for higher-accuracy applications where extended low-temp operation is not required. |
| ADR4550BRZ | 0.02% initial accuracy, 3ppm/°C drift, 1.75ppmP-P noise, ±10mA drive, SOIC-8 package | Superior accuracy and drift, but only rated to –40°C to 125°C; no AEC-Q100 certification | Choose when ultimate precision is needed and automotive qualification is not mandatory. |
Compared with REF5050QPWRQ1 and ADR4550BRZ, the LT6654BMPS6-5#TRPBF trades minor noise and drift penalties for guaranteed –55°C operation, AEC-Q100 qualification, and TSOT-23 space savings-making it uniquely suited for compact, high-reliability automotive and aerospace designs where extended temperature range is non-negotiable.

FAQ
What is the maximum input voltage for the LT6654BMPS6-5#TRPBF?
The LT6654BMPS6-5#TRPBF supports an absolute maximum input voltage of 38V, with full operational specification up to 36V. Operation at 36V enables direct connection to unregulated industrial or automotive power rails without pre-regulation, while maintaining ±0.10% output accuracy and 20ppm/°C drift performance across –55°C to 125°C.
Does the LT6654BMPS6-5#TRPBF support sinking current, and how does that affect its use?
Yes, the LT6654BMPS6-5#TRPBF can sink up to 10mA, enabling its use as a precision negative voltage reference when configured with appropriate external circuitry. This bidirectional capability eliminates the need for separate positive/negative references in dual-supply systems, and its 20ppm/mA sinking load regulation ensures predictable performance even under dynamic load conditions.
How does the thermal hysteresis of the LT6654BMPS6-5#TRPBF impact long-term measurement stability?
The LT6654BMPS6-5#TRPBF exhibits 50ppm thermal hysteresis over –55°C to 125°C in the TSOT-23 package, meaning output voltage may shift by up to ±250µV after repeated thermal cycling. This is fully characterized and included in total error budgets for applications like battery monitoring and downhole sensing, where calibration intervals account for hysteresis as a deterministic, bounded error term.
Can the LT6654BMPS6-5#TRPBF be used in AEC-Q100 automotive applications?
Yes, the LT6654BMPS6-5#TRPBF is explicitly AEC-Q100 qualified for automotive applications. Its MP-grade temperature range (–55°C to 125°C), robust construction, and tested reliability metrics-including HTOL, TC, and UHAST-make it suitable for engine control units, battery management systems, and ADAS sensor interfaces requiring ASIL-B compliance evidence.
What is the recommended output capacitance for stable operation of the LT6654BMPS6-5#TRPBF?
An output capacitor of at least 1µF is required for stable operation of the LT6654BMPS6-5#TRPBF. Ceramic X7R or C0G types are preferred; larger values (e.g., 10µF) improve PSRR and transient response but increase turn-on time. The 1µF value balances stability, speed (150µs typical turn-on), and board space-critical for portable and high-density automotive modules.
