Product details
Overview
The MAX6030BEUR from Maxim Integrated is a precision, low-dropout, micropower series-mode voltage reference in SOT23-3 packaging, delivering a stable 3.000V output with ±0.006V (0.2%) initial accuracy, <15ppm/°C temperature coefficient, and 100mV dropout at 500µA load-optimized for battery-operated instrumentation and portable data acquisition systems.
For engineers reviewing the MAX6030BEUR datasheet, MAX6030BEUR pinout, MAX6030BEUR application, or MAX6030BEUR equivalent, key selection criteria include its supply-current independence (0.8µA/V variation), ±500µA sourcing/sinking capability, stability with up to 2.2nF capacitive load, and operation across –40°C to +85°C without external compensation.
Technical Context
This device implements a curvature-corrected bandgap architecture with laser-trimmed thin-film resistors to achieve high initial accuracy and low thermal drift. It operates as a three-terminal series reference, eliminating the need for external biasing resistors or compensation capacitors.
Its input voltage range is (VOUT + 0.2V) to 12.6V, supporting low-voltage systems down to 3.2V supply while maintaining regulation. Load regulation is specified at 0.14µV/µA, and line regulation at 20µV/V over full temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARJZ-R7 | 3.0V output, 10ppm/°C TC, 30µA IQ, but requires 1µF output capacitor for stability | Higher accuracy but larger board footprint due to mandatory capacitor | Select when lower TC and tighter long-term drift (<15ppm/1000hr) outweigh capacitor requirement |
| REF3330AIDBVR | 3.0V output, 12ppm/°C TC, 3.9µA IQ, 150mV dropout, limited to 10mA load | Ultra-low power but higher dropout and no sink capability | Select for sub-10µA systems where load current is sourcing-only and supply headroom >150mV |
Compared with ADR3430ARJZ-R7 and REF3330AIDBVR, the MAX6030BEUR uniquely combines ±500µA bidirectional drive, capacitor-free stability, and 100mV dropout-making it optimal for compact, bidirectional analog interfaces in 3.3V domains.

FAQ
What is the maximum load current the MAX6030BEUR can source and sink?
The MAX6030BEUR can source and sink up to ±500µA while maintaining output regulation within specifications. This bidirectional capability eliminates the need for external op-amp buffers in many sensor interface and DAC reference applications, directly driving ADC reference inputs or precision current sources. The MAX6030BEUR maintains 0.2% accuracy across this full load range under all operating conditions.
Does the MAX6030BEUR require an external output capacitor for stability?
No, the MAX6030BEUR is internally compensated and stable with capacitive loads from 0 to 2.2nF-no external capacitor is required. This design eliminates board area and cost associated with stabilization components. While adding up to 2.2nF may improve transient response in step-load scenarios, the MAX6030BEUR delivers full-spec performance with zero external capacitance.
What is the minimum input voltage required for regulation of the MAX6030BEUR?
The MAX6030BEUR requires a minimum input voltage of (VOUT + 0.2V) = 3.2V to maintain regulation. Its 100mV dropout voltage at 500µA load means it operates reliably down to 3.2V supply-ideal for 3.3V systems experiencing rail droop during peak current events. Below 3.2V, output voltage drops nonlinearly and regulation is not guaranteed.
How does the supply current of the MAX6030BEUR vary with input voltage?
The MAX6030BEUR exhibits exceptional supply-current stability: quiescent current varies by only 0.8µA per volt of input voltage change (0.8µA/V). At 3.2V input, IQ is ~27µA; at 12.6V, it rises to ~35µA max. This near-constant current draw maximizes battery efficiency across wide supply ranges-unlike shunt references whose current scales linearly with VIN.
What is the temperature coefficient specification for the MAX6030BEUR over its full operating range?
The MAX6030BEUR has a maximum temperature coefficient of <15ppm/°C over the full –40°C to +85°C industrial temperature range, measured using the "box method" (maximum ∆VOUT divided by maximum ∆T). This ensures output voltage deviation remains below ±1.2mV across the entire range, critical for high-resolution data acquisition where reference drift dominates system error budgets.
