Product details
Overview
MAX6023EBT25-T from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference IC delivering a stable 2.500V output with ±0.20% initial accuracy and 30ppm/°C max temperature coefficient over –40°C to +85°C. It operates from (VOUT + 0.2V) to 12.6V input, draws only 35µA max supply current, and maintains stability with up to 2.2nF capacitive load - ideal for high-accuracy ADC/DAC biasing in portable instrumentation.
For engineers reviewing the MAX6023EBT25-T datasheet, MAX6023EBT25-T pinout, MAX6023EBT25-T application, or MAX6023EBT25-T equivalent, this page delivers verified specifications, UCSP-5 package layout, real-world use cases in battery-powered data acquisition, and two validated alternative references with documented technical and application differences.
Technical Context
The MAX6023EBT25-T uses a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift and ±0.20% initial accuracy. Its series-mode architecture enables sourcing/sinking up to ±500µA while maintaining dropout as low as 100mV at 500µA load.
Internally compensated and capacitor-free stable, it exhibits 140µV/V max line regulation and 0.8µA/V supply current variation across input voltage - enabling predictable power budgeting in wide-input-voltage systems such as industrial sensors and handheld test equipment.
Key Specifications

| Initial Accuracy | ±0.20% - eliminates need for system-level calibration in portable medical sensors and portable DMMs. |
| Temp Coefficient | ≤30ppm/°C - ensures <±0.75mV drift over –40°C to +85°C, critical for unheated outdoor process transmitters. |
| Dropout Voltage | 100mV at 500µA load - supports operation from 2.6V input, enabling direct use with single Li-ion cells (2.7–4.2V). |
| Supply Current | 35µA max - extends battery life beyond 10 years in low-duty-cycle IoT sensor nodes powered by CR2032. |
| Load Capacitance | Stable with 0–2.2nF - allows direct connection to ADC input capacitance without external compensation. |
| Line Regulation | 140µV/V max - minimizes output shift during battery discharge or unregulated DC-DC ripple. |
Pinout & Package
MAX6023EBT25-T uses a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), optimized for ultra-low profile and minimal PCB footprint. Bump pitch is 0.5mm; bumps are on bottom side only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected on PCB - no routing or solder mask opening required. |
| A2 | GND | Reference ground return path; requires low-impedance connection to system AGND plane for noise immunity. |
| B1 | OUT | 2.500V precision output; directly drives ADC REF+ pins or op-amp non-inverting inputs without buffering. |
| B3 | IN | Input voltage terminal; accepts (2.7V–12.6V) range; decoupling capacitor recommended within 2mm of bump. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3025AIDBZR | 2.5V output, ±0.2% initial accuracy, 50ppm/°C drift, SOT23-3 package, 50µA supply current. | Higher tempco and larger footprint limit use in extended-temp industrial sensors; better suited for cost-sensitive consumer electronics. | Select when SOT23 assembly infrastructure exists and 50ppm/°C drift is acceptable for <85°C applications. |
| ADR3425ARJZ-R7 | 2.5V output, ±0.1% initial accuracy, 10ppm/°C drift, SOT23-5 package, 120µA supply current, higher cost. | Superior accuracy and stability justify use in metrology-grade instruments but increase power consumption 3.4× vs. MAX6023EBT25-T. | Select when sub-10ppm/°C drift and ±0.1% accuracy are mandatory, and supply current >100µA is tolerable. |
Compared with REF3025AIDBZR, MAX6023EBT25-T offers tighter thermal stability (30ppm/°C vs. 50ppm/°C) and lower power (35µA vs. 50µA); compared with ADR3425ARJZ-R7, it trades 0.1% accuracy and 10ppm/°C drift for 3.4× lower supply current and 40% smaller footprint - making it optimal for battery-critical, space-constrained industrial sensing.

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT25-T?
The MAX6023EBT25-T requires a minimum input voltage of (VOUT + 0.2V) = 2.7V for guaranteed specification compliance across temperature. Below this, dropout increases and output accuracy degrades. At 2.6V input, the device may still regulate but with reduced margin - design verification at worst-case VIN is recommended for production use of MAX6023EBT25-T.
Does the MAX6023EBT25-T require an external output capacitor?
No, the MAX6023EBT25-T is internally compensated and stable with 0–2.2nF output capacitance, so no external capacitor is required for basic operation. However, adding a 100pF–1nF ceramic capacitor near the OUT bump improves transient response during fast load steps - especially beneficial in multiplexed ADC systems where MAX6023EBT25-T supplies multiple channels sequentially.
Can the MAX6023EBT25-T source and sink current simultaneously?
Yes, the MAX6023EBT25-T is a three-terminal series-mode reference capable of sourcing up to +500µA into a light load and sinking up to –500µA from a heavy load, with <200mV dropout. This bidirectional capability allows it to drive both high-impedance ADC references and low-impedance op-amp bias networks - a key advantage over shunt references in complex analog signal chains using MAX6023EBT25-T.
What is the maximum capacitive load the MAX6023EBT25-T can drive while remaining stable?
The MAX6023EBT25-T is guaranteed stable with output capacitive loads from 0 to 2.2nF, per the datasheet's "Capacitive-Load Stability Range" specification. Loads exceeding 2.2nF may cause peaking or oscillation. For applications requiring >2.2nF (e.g., long PCB traces or large ADC input capacitance), a small series resistor (1–10Ω) between MAX6023EBT25-T OUT and the load restores stability without degrading DC accuracy.
How does supply current vary with input voltage for the MAX6023EBT25-T?
The MAX6023EBT25-T exhibits only 0.8µA/V maximum change in supply current across its input voltage range of 2.7V to 12.6V. This near-constant current draw - unlike shunt references that waste current - enables accurate battery-life estimation in portable systems. At 5V input, typical supply current is 27µA; at 12V, it rises to ≤35µA, confirming predictable power behavior essential for firmware-based power management in MAX6023EBT25-T–based designs.
