Product details
Overview
MAX6061BEUR from Maxim Integrated is a precision, micropower, low-dropout series voltage reference in SOT23-3 package, delivering 1.248V output with ±0.48% initial accuracy, 30ppm/°C max temperature coefficient, and 90µA typical quiescent current. It sources up to 5mA or sinks 2mA, operates from 2.5V to 12.6V input, and supports battery-powered precision ADCs and portable instrumentation.
For engineers reviewing the MAX6061BEUR datasheet, MAX6061BEUR pinout, MAX6061BEUR application, or MAX6061BEUR equivalent, key selection criteria include its 1.248V nominal output, 200mV max dropout at 1mA, no-output-capacitor operation, 13µVp-p (0.1Hz–10Hz) noise, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX6061BEUR employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve high initial accuracy and low thermal drift. Its BiCMOS process enables stable operation without external compensation capacitors while maintaining ultra-low supply current independent of input voltage (≤8µA/V variation).
This series-mode reference features internal compensation, stable performance with capacitive loads, and robust transient response-settling to 0.1% in 50µs with 50pF load. Dropout voltage remains ≤200mV at 1mA load, enabling use in low-voltage systems where headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.248V (nominal), ±0.48% initial tolerance - ensures accurate scaling for 12-bit+ ADCs without calibration. |
| Temp Coefficient | ≤30ppm/°C - limits output drift to <±0.25mV over –40°C to +85°C ambient range. |
| Quiescent Current | 90µA (typ), ≤125µA (max) - extends battery life in always-on sensor nodes and portable meters. |
| Dropout Voltage | ≤200mV at 1mA load - allows operation from 1.45V supply, compatible with single-cell Li-ion or alkaline systems. |
| Noise (0.1–10Hz) | 13µVp-p - minimizes quantization error in high-resolution data acquisition front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3012IDBZR | 1.2V output, ±0.5% initial accuracy, 50ppm/°C tempco, 50µA IQ, SOT23-3 | Lower accuracy and higher drift; better for cost-sensitive, non-critical references | Select when 1.2V output suffices and tighter drift is not required; lower IQ benefits ultra-low-power sleep modes. |
| ADR3412ARJZ-R7 | 1.2V output, ±0.1% initial accuracy, 10ppm/°C tempco, 120µA IQ, SOT23-3 | Higher accuracy and lower drift, but 33% higher supply current and higher cost | Choose for metrology-grade systems requiring <±0.05% total error over temperature; verify layout for PSRR sensitivity. |
Compared with REF3012IDBZR, MAX6061BEUR offers tighter initial accuracy and lower tempco at modest IQ penalty; versus ADR3412ARJZ-R7, it trades 0.3% accuracy and 20ppm/°C drift for 30% lower quiescent current and proven robustness in high-EMI portable designs.

FAQ
What is the output voltage tolerance and temperature coefficient of MAX6061BEUR?
The MAX6061BEUR has a nominal output voltage of 1.248V with ±0.48% initial accuracy (B-grade) and a maximum temperature coefficient of 30ppm/°C over –40°C to +85°C. These specifications are fully tested and guaranteed per the datasheet's electrical characteristics table for the MAX6061B variant. The MAX6061BEUR achieves this performance using laser-trimmed thin-film resistors and curvature-correction circuitry.
Does MAX6061BEUR require an external output capacitor for stability?
No, MAX6061BEUR does not require an external output capacitor for stability due to its internally compensated architecture. It remains stable with capacitive loads from 0 to at least 1µF. An optional 0.1µF ceramic capacitor may be added to improve transient response in high-step-load applications, but it is not necessary for basic operation - a key advantage for ultra-compact PCB layouts.
What is the minimum input voltage required for proper regulation of MAX6061BEUR?
The minimum input voltage for MAX6061BEUR is 2.5V, as specified in the Selector Guide and Absolute Maximum Ratings. At 1mA load, dropout is guaranteed ≤200mV, meaning regulation is maintained down to VIN = VOUT + 200mV = 1.448V - however, the device is only characterized and guaranteed for operation above 2.5V input. Operation below 2.5V may result in undefined behavior or failure to regulate.
How does the supply current of MAX6061BEUR vary with input voltage?
MAX6061BEUR exhibits highly stable quiescent supply current: typical 90µA with ≤8µA/V variation across the 2.5V–12.6V input range. This near-constant current draw - unlike shunt references whose current scales with VIN - maximizes efficiency in battery systems and simplifies power budgeting. Measured data shows <±5µA change from 5V to 12V input under no-load conditions.
Can MAX6061BEUR sink current, and what is its maximum sink capability?
Yes, MAX6061BEUR can both source and sink current. It is rated to sink up to 2mA while maintaining output regulation and specified accuracy. This bidirectional capability enables use in active bias networks, current-steering DACs, and circuits requiring dynamic load adjustment - such as programmable gain amplifier references or precision current sources where the reference node must absorb reverse current.
