Product details
Overview
TSM6025BEUR+T from Silicon Laboratories is a 3-terminal, series-mode 2.5 V precision voltage reference with 0.4% initial accuracy, 25 ppm/°C max temperature coefficient, and ±500 μA output drive capability. It operates from 2.7 V to 12.6 V input, delivers low dropout (100 mV at 500 μA), and targets high-accuracy analog signal chains in battery-powered instrumentation and industrial transmitters.
For engineers reviewing the TSM6025BEUR+T datasheet, TSM6025BEUR+T pinout, TSM6025BEUR+T application, or TSM6025BEUR+T equivalent, key selection criteria include initial accuracy vs. temperature drift trade-offs, capacitive-load stability up to 2200 pF, quiescent current ≤35 μA, and compatibility with low-headroom 3V/5V systems requiring stable 2.5 V references.
Technical Context
The TSM6025BEUR+T integrates a proprietary low-drift bandgap core followed by a unity-gain output amplifier optimized for low headroom and wide capacitive-load tolerance. Its series-mode architecture eliminates external bias resistors and ensures supply current remains stable across input voltage variations (ΔIIN/ΔVIN < 2.0 μA/V).
It achieves thermal stability via matched transistor design and stress-compensated packaging, delivering 130 ppm typical temperature hysteresis and 50 ppm/1000 hr long-term drift. The output stage supports bidirectional 500 μA load current without external compensation while maintaining 0.14 μV/μA load regulation and 140 μV/V line regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±0.4% at +25°C - guarantees absolute accuracy within ±10 mV for calibration-critical ADC/DAC biasing |
| Temp Coefficient | 25 ppm/°C max (–40°C to +85°C) - limits output drift to ±2.1 mV over full industrial temperature range |
| Quiescent Current | 35 μA max - enables multi-year operation from coin-cell batteries in portable data loggers |
| Dropout Voltage | 100 mV at 500 μA load - allows use with 2.6 V supplies in ultra-low-voltage 3V systems |
| Capacitive Load Stability | 0–2200 pF - eliminates need for external compensation, simplifying layout in noise-sensitive sensor front-ends |
| Line Regulation | 140 μV/V - ensures <0.35 mV output shift per volt of input variation, critical for unregulated power rails |
| Load Regulation | 0.14 μV/μA sourcing - maintains sub-70 μV error across full 500 μA load range, supporting precision current sources |
Pinout & Package
Supplied in a 3-pin SOT23 package (2.92 mm × 1.3 mm × 1.0 mm), the TSM6025BEUR+T uses standard JEDEC MO-203AA outline with gull-wing leads and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts 2.7 V to 12.6 V; internal series regulator draws only 35 μA regardless of VIN - no external resistor required |
| 2 (OUT) | 2.5 V Reference Output | Provides low-impedance, bidirectional ±500 μA drive; stable with 0–2200 pF capacitive loads |
| 3 (GND) | Analog Ground Reference | Must be connected to clean system ground plane; separates reference return from digital or power ground currents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6025BEUR+T | Pin-for-pin compatible; identical 0.4% accuracy and 25 ppm/°C spec; same SOT23-3 package and electrical behavior | No functional or layout changes required; drop-in replacement verified by Silicon Labs documentation | Select when legacy MAXIM design reuse or dual-sourcing strategy is required |
| REF3025AIDBZR | 0.2% initial accuracy, 50 ppm/°C max tempco; 45 μA max IQ; requires ≥1.5 V headroom (dropout ~150 mV at 500 μA) | Higher accuracy but worse tempco; slightly higher quiescent current; less tolerant of low-input-voltage conditions | Select when tighter initial tolerance is prioritized over temperature stability and ultra-low dropout |
Compared with MAX6025BEUR+T, the TSM6025BEUR+T offers identical performance and footprint, enabling seamless second-source qualification; versus REF3025AIDBZR, it trades 0.2% initial accuracy for superior thermal stability and lower dropout-critical in wide-temperature industrial deployments.

FAQ
What is the guaranteed initial accuracy of the TSM6025BEUR+T over temperature?
The TSM6025BEUR+T guarantees ±0.4% initial output voltage accuracy at +25°C, with full specification over –40°C to +85°C. Its maximum temperature coefficient is 25 ppm/°C across that range, resulting in a worst-case total drift of ±2.1 mV. This performance is validated per the "box method" defined in the datasheet and applies directly to the TSM6025BEUR+T device marking ACY.
Can the TSM6025BEUR+T drive a 1000 pF capacitive load without oscillation?
Yes, the TSM6025BEUR+T is fully stable with capacitive loads from 0 pF up to 2200 pF, including 1000 pF. No external series resistor or compensation network is required. This capability is confirmed in the Electrical Characteristics table (Capacitive-Load Stability Range = 0–2.2 nF) and supported by the internal frequency compensation design described in the Theory of Operation section of the TSM6025BEUR+T datasheet.
How does the supply current of the TSM6025BEUR+T vary with input voltage?
The TSM6025BEUR+T exhibits minimal supply current variation with input voltage: ΔIIN/ΔVIN is guaranteed ≤2.0 μA/V across its full operating range (VOUT + 0.2 V ≤ VIN ≤ 12.6 V). At nominal conditions (VIN = 5 V), quiescent current is typically 27 μA and never exceeds 35 μA - a key advantage of its series-mode architecture over shunt references.
Is the TSM6025BEUR+T pin-compatible with the MAX6025 series?
Yes, the TSM6025BEUR+T is explicitly designed as a pin-for-pin alternate source for the MAX6025 voltage reference. Both devices use identical 3-pin SOT23 packaging, share identical pin functions (IN, OUT, GND), and match on all key electrical parameters including accuracy, tempco, dropout, and load drive. Silicon Labs confirms this compatibility in the TSM6025BEUR+T product description and features list.
What is the maximum continuous output current the TSM6025BEUR+T can source or sink?
The TSM6025BEUR+T can continuously source or sink up to ±500 μA while maintaining specified accuracy and stability. This is confirmed in both the Features list ("Output Source/Sink Current: ±500μA") and the Electrical Characteristics table (Load Regulation test conditions). Exceeding this current may degrade output voltage regulation or increase dropout beyond specifications.
