Product details
Overview
MAX6023EBT25 from Maxim Integrated is a precision, low-dropout, micropower series-mode voltage reference IC in a 5-bump UCSP package, delivering 2.500V ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA load - optimized for high-accuracy analog signal conditioning in battery-powered data acquisition systems.
For engineers reviewing the MAX6023EBT25 datasheet, MAX6023EBT25 pinout, MAX6023EBT25 application, or MAX6023EBT25 equivalent, key selection criteria include its ultra-low 35µA quiescent current, input voltage range of (VOUT + 0.2V) to 12.6V, stability with up to 2.2nF capacitive load, and chip-scale footprint ideal for space-constrained industrial sensors and portable instrumentation.
Technical Context
The MAX6023EBT25 implements a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift over –40°C to +85°C. It operates as a three-terminal series-mode reference, sourcing/sinking ±500µA while maintaining regulation under 200mV dropout.
Its supply current varies only 0.8µA/V across input voltage, enabling predictable power budgeting in wide-input-voltage systems. Internally compensated design eliminates need for external output capacitor, yet remains stable with 0–2.2nF load capacitance - critical for fast transient response in ADC biasing and sensor excitation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.2% at +25°C - enables direct interface with 2.5V ADC references and precision DACs without trimming. |
| Temperature Coefficient | ≤30ppm/°C - ensures ≤±0.625mV drift over full –40°C to +85°C range for stable sensor calibration. |
| Dropout Voltage | 100mV at 500µA load - supports operation from 2.6V input, compatible with single-cell Li-ion or 3.3V LDO outputs. |
| Quiescent Current | 27µA typical / 35µA max - extends battery life in multidecade standby applications like remote data loggers. |
| Line Regulation | ≤140µV/V - limits output change to <175µV over 2.7V–12.6V input swing, critical for unregulated supply rejection. |
| Load Regulation | ≤0.8µV/µA - maintains <400µV shift across full ±500µA load range, suitable for driving op-amp inputs and SAR ADC references. |
| Noise (0.1–10Hz) | 60µVp-p - low enough for 16-bit+ resolution in precision weigh scales and medical front-ends. |
Pinout & Package
MAX6023EBT25 uses a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), offering the smallest footprint among Maxim's precision references - ideal for height-critical PCB layouts where SC70 or SOT23 are too tall.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected bumps - must remain unconnected on PCB; no routing or solder mask opening required. |
| A2 | GND | Reference ground terminal - requires low-impedance connection to system analog ground plane for noise immunity. |
| B1 | OUT | Precision 2.500V output - directly drives ADC reference inputs, op-amp bias networks, or sensor bridge excitation. |
| B3 | IN | Input voltage terminal - accepts (VOUT + 0.2V) to 12.6V; internal current limiting protects against overvoltage during startup. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with 0–2.2nF load capacitance - eliminates BOM cost and layout area for decoupling caps in compact sensor nodes. |
| Ultra-low supply current variation | 0.8µA/V ∆IIN/∆VIN - enables accurate battery-life estimation across wide input ranges in energy-harvesting systems. |
| Low-profile UCSP packaging | 0.3mm height - allows placement beneath connectors or in stacked modules where vertical clearance is limited to <0.5mm. |
| Guaranteed initial accuracy | ±0.2% at +25°C - reduces or eliminates factory calibration steps in production test for portable test equipment. |
| Short-circuit protection | Continuous short-to-GND or short-to-IN (VIN < 6V) - enhances robustness in field-deployed industrial controllers exposed to wiring faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425BRJZ-R7 | 2.5V output, ±0.1% initial accuracy, 30ppm/°C drift, 125µA max supply current, SOT23-5 package (2.9mm × 1.6mm). | Higher supply current reduces battery life in ultra-low-power designs; larger footprint constrains dense sensor arrays. | Select when higher initial accuracy justifies trade-offs in power and size; not drop-in due to different pinout and package. |
| REF3325AIDBVR | 2.5V output, ±0.2% initial accuracy, 30ppm/°C drift, 4.5µA typical supply current, SOT23-3 package (2.9mm × 1.6mm), but requires 1µF output capacitor. | Lower quiescent current benefits multi-year battery life, but external capacitor increases board area and complicates layout in tight spaces. | Select for longest battery life where capacitor placement is feasible; incompatible pinout and compensation requirements prevent direct replacement. |
Compared with ADR3425BRJZ-R7 and REF3325AIDBVR, MAX6023EBT25 uniquely balances ultra-low profile (0.3mm), no-capacitor operation, and 35µA supply current - making it optimal for miniaturized, battery-constrained systems where both height and component count are critical.

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT25?
The MAX6023EBT25 requires a minimum input voltage of (VOUT + 0.2V), i.e., 2.7V, to maintain regulation at full load. Below this, dropout behavior occurs - output voltage drops linearly with input. This 200mV headroom enables compatibility with low-voltage rails such as those from single-cell Li-ion batteries or post-LDO supplies. The MAX6023EBT25 datasheet specifies guaranteed performance from 2.7V to 12.6V.
Does the MAX6023EBT25 require an external output capacitor for stability?
No, the MAX6023EBT25 is internally compensated and stable with 0–2.2nF capacitive load - no external capacitor is required for basic operation. An optional capacitor may be added to improve transient response during large load steps, but it is not needed for oscillation-free DC regulation. This eliminates BOM cost and PCB area, a key advantage in ultra-compact designs using the MAX6023EBT25.
What is the maximum load current the MAX6023EBT25 can source or sink while maintaining regulation?
The MAX6023EBT25 is specified to source and sink up to ±500µA while maintaining output voltage regulation within datasheet limits. At 500µA load, dropout voltage is guaranteed ≤200mV. Exceeding ±500µA may cause output deviation beyond the 0.2% initial accuracy band. For applications requiring higher drive capability, the MAX6023EBT25 should be buffered with an op-amp.
How does supply current vary with input voltage for the MAX6023EBT25?
The MAX6023EBT25 exhibits exceptionally stable supply current: it varies by only 0.8µA per volt of input voltage change (max), over its operating range of 2.7V to 12.6V. This near-constant current draw - 27µA typical, 35µA max - simplifies power budgeting and enables accurate battery-life prediction in variable-input systems, a distinct advantage over shunt references or less-regulated series references.
Is the MAX6023EBT25 pin-compatible with other members of the MAX6023 family?
Yes, all MAX6023 variants - including MAX6023EBT12, MAX6023EBT21, MAX6023EBT25, MAX6023EBT30, MAX6023EBT41, MAX6023EBT45, and MAX6023EBT50 - share identical 5-bump UCSP package, pinout, and footprint. Only the output voltage differs (1.25V to 5.0V). This allows design reuse across voltage-scaled systems - for example, substituting MAX6023EBT25 for MAX6023EBT30 requires only a BOM change, no PCB revision.
