Product details
Overview
TSM6025AEUR+T from Silicon Laboratories is a 3-terminal, series-mode 2.5 V precision voltage reference with 0.2% initial accuracy, 15 ppm/°C max temperature coefficient, and 35 μA max quiescent current. It operates over –40°C to +85°C, delivers ±500 μA load current, and maintains stability with capacitive loads up to 2200 pF - ideal for high-accuracy data acquisition and battery-powered instrumentation.
For engineers reviewing the TSM6025AEUR+T datasheet, TSM6025AEUR+T pinout, TSM6025AEUR+T application, or TSM6025AEUR+T equivalent, key selection criteria include low dropout (100 mV at 500 μA), minimal line regulation (25 μV/V), and guaranteed performance in industrial temperature ranges without external compensation.
Technical Context
The TSM6025AEUR+T integrates a proprietary low-drift bandgap core followed by a unity-gain output amplifier optimized for low headroom and capacitive-load stability. Its series architecture eliminates dependency on external bias resistors and ensures supply current remains stable across input voltage variations.
It achieves 0.14 μV/μA load regulation and 140 μV/V line regulation while supporting sourcing and sinking up to ±500 μA - enabling direct interface with ADC references, DAC buffers, and sensor signal chains without additional buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±0.2% (2.495–2.505 V) at +25°C - enables 16-bit ADC reference accuracy without trimming |
| Temp Coefficient | 15 ppm/°C max (–40°C to +85°C) - contributes ≤0.75 mV drift over full range, critical for process-control transmitters |
| Quiescent Current | 35 μA max - supports >10-year battery life in 10 μA-sleep-cycle portable meters |
| Dropout Voltage | 100 mV at 500 μA load - allows operation from 2.6 V supply in 3 V systems with margin |
| Capacitive Load Stability | Stable up to 2200 pF - eliminates need for external compensation in noisy industrial PCB layouts |
| Line Regulation | 25 μV/V - limits output shift to <300 μV across 2.7–12.6 V input range |

Pinout & Package
Supplied in a 3-pin SOT23 package (2.92 mm × 1.3 mm × 1.0 mm), surface-mount compatible with standard reflow profiles and IPC-7351B footprint MS-012AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Voltage Input | Accepts 2.7 V to 12.6 V; internal series regulator rejects ripple and enables stable reference under varying rail conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6025AESA+ | Same 0.2% accuracy and 15 ppm/°C TC, but 40 μA max quiescent current and 3-pin SOIC package (larger footprint) | Preferred where board space permits and legacy SOIC assembly lines are used | Select when compatibility with existing MAX6025-based SOIC footprints is required; not pin-compatible with SOT23 |
| ADR3425ARJZ-R7 | 0.1% initial accuracy, 10 ppm/°C TC, but 4.5 μA typical quiescent current and requires ≥1.5 V headroom (dropout ~250 mV at 500 μA) | Better accuracy and lower power, but higher dropout limits use in 2.7 V systems | Choose for highest-accuracy battery-critical apps where supply >2.75 V; verify layout clearance for different SOT23 marking and thermal pad |
Compared with MAX6025AESA+, the TSM6025AEUR+T offers identical electrical specs in a smaller SOT23 package and lower max supply current; compared with ADR3425ARJZ-R7, it trades 0.1% accuracy for guaranteed 100 mV dropout and broader input voltage range - favoring ruggedness over ultimate precision in industrial environments.

FAQ
What is the operating temperature range for the TSM6025AEUR+T?
The TSM6025AEUR+T is fully specified over the industrial temperature range of –40°C to +85°C. All key parameters - including initial accuracy, temperature coefficient, line regulation, and load regulation - are guaranteed across this range per the official Silicon Labs datasheet Rev. 1.0. This makes the TSM6025AEUR+T suitable for deployment in outdoor process transmitters and factory-floor data loggers without derating.
Is the TSM6025AEUR+T pin-compatible with the MAX6025A?
Yes, the TSM6025AEUR+T is explicitly designed as a pin-for-pin alternate source for the MAX6025 voltage reference. Both devices share identical 3-pin SOT23 pinout (IN, OUT, GND), same electrical specifications (0.2% accuracy, 15 ppm/°C TC), and matching footprint dimensions - enabling direct replacement without PCB modification or firmware changes.
Does the TSM6025AEUR+T require an external output capacitor?
No, the TSM6025AEUR+T does not require an external output capacitor for stability. It is internally compensated and remains stable with capacitive loads up to 2200 pF. An optional output capacitor (e.g., 10 nF ceramic) may be added to improve large-signal transient response in high-dynamic-range data acquisition systems, but it is not necessary for basic functionality or stability.
What is the maximum load current the TSM6025AEUR+T can source or sink?
The TSM6025AEUR+T can source and sink up to ±500 μA while maintaining output voltage regulation within specification. At 500 μA load, dropout voltage remains ≤200 mV (typical 100 mV), and load regulation is specified at 0.14 μV/μA for sourcing and 0.18 μV/μA for sinking - ensuring predictable behavior when driving ADC reference inputs or op-amp bias networks.
How does the supply current of the TSM6025AEUR+T vary with input voltage?
The TSM6025AEUR+T exhibits exceptionally low supply current variation: <1 μA/V across its full input range (VOUT + 0.2 V to 12.6 V). Its maximum quiescent current is 35 μA, and typical no-load current is 27 μA at +25°C. This near-constant current draw - inherent to its series-mode architecture - simplifies power budgeting and eliminates the VIN-dependent current drift seen in shunt-mode references.
