Product details
Overview
MAX6023EBT25+T from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference in a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), delivering a stable 2.500V output with ±0.20% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA 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, key selection criteria include micropower operation (35µA max supply current), no-output-capacitor stability up to 2.2nF, input voltage range of (VOUT + 0.2V) to 12.6V, and UCSP footprint constraints for space-constrained PCB layouts.
Technical Context
The MAX6023EBT25+T uses a laser-trimmed thin-film resistor and proprietary curvature-corrected bandgap core to achieve <30ppm/°C drift and ±0.20% initial accuracy across –40°C to +85°C. It operates as a three-terminal series-mode reference, sourcing/sinking up to ±500µA while maintaining regulation.
Its internal compensation eliminates need for external capacitors; stability is guaranteed from 0 to 2.2nF load capacitance. Supply current variation is tightly controlled at ≤0.8µA/V over input voltage, enabling predictable battery-life estimation in energy-sensitive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.20% at +25°C - ensures precise full-scale reference for 12-bit+ SAR ADCs without calibration. |
| Temperature Coefficient | ≤30ppm/°C - limits output drift to <±75µV over –40°C to +85°C, critical for industrial sensor front-ends. |
| Dropout Voltage | 100mV at 500µA load - enables operation from 2.6V supply, supporting single-cell Li-ion or 3.3V rail margin. |
| Supply Current | ≤35µA - extends battery life in handheld meters; variation ≤0.8µA/V simplifies power budgeting. |
| Line Regulation | ≤140µV/V - suppresses supply ripple impact on reference accuracy, easing LDO selection. |
| Load Regulation | ≤1.4µV/µA - maintains stability under dynamic load shifts typical in multiplexed data acquisition. |
| Noise (10Hz–10kHz) | 125µVRMS - low enough for 16-bit sigma-delta ADCs without additional filtering. |
Pinout & Package
MAX6023EBT25+T uses a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), optimized for ultra-low profile and minimal PCB area. Bumps are on the bottom side; top-side markings include "AAP".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected on PCB - floating bumps prevent unintended shorts. |
| A2 | GND | Reference ground return path; requires low-impedance connection to system AGND plane. |
| B1 | OUT | Stable 2.500V reference output; routed with short, low-inductance trace to ADC REF+ or DAC VREF. |
| B3 | IN | Input supply (2.7V min); decoupling capacitor recommended near bump for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–2.2nF load capacitance - eliminates board space and cost of external C, critical for wearables. |
| Low dropout voltage | 100mV at 500µA - enables direct regulation from low-voltage rails without cascaded LDOs. |
| Micropower operation | 35µA max supply current - supports >1-year battery life in 10µA-average-current IoT sensors. |
| Laser-trimmed accuracy | ±0.20% initial tolerance - reduces system calibration steps and improves production yield. |
| UCSP footprint | 1.0mm × 1.5mm area - occupies ~30% less space than SOT23-3, enabling dense mixed-signal layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the minimum input voltage required for stable operation of MAX6023EBT25+T?
The MAX6023EBT25+T requires a minimum input voltage of (VOUT + 0.2V) = 2.7V to maintain regulation. Below this, output voltage drops nonlinearly. At 500µA load, dropout is specified at 100mV - meaning 2.6V input sustains 2.5V output, but full specifications apply only above 2.7V per datasheet conditions.
Does MAX6023EBT25+T require an external output capacitor?
No, MAX6023EBT25+T is internally compensated and stable with 0–2.2nF load capacitance. An external capacitor is optional and only recommended in applications with fast load or supply transients to reduce overshoot - it is not needed for basic regulation stability.
What is the thermal performance of MAX6023EBT25+T in its UCSP package?
MAX6023EBT25+T is rated for –40°C to +85°C operation. Its UCSP package has low thermal mass but relies on PCB copper for heat dissipation; junction-to-board thermal resistance is ~120°C/W. Power dissipation must stay below 273mW at +70°C ambient, derating 3.4mW/°C above that.
How does supply current vary with input voltage for MAX6023EBT25+T?
MAX6023EBT25+T exhibits ≤0.8µA/V change in supply current over its input range (2.7V to 12.6V). At 2.7V, typical IIN is 27µA; at 12.6V, it rises by ≤8µA - enabling accurate battery-life modeling without complex voltage-dependent calculations.
Can MAX6023EBT25+T drive a 500µA load while maintaining specification?
Yes, MAX6023EBT25+T is fully specified to source or sink up to ±500µA. At 500µA load, dropout remains ≤200mV, line/load regulation stays within datasheet limits, and output voltage accuracy holds to ±0.20% initial tolerance plus temperature drift contribution.
