Product details
Overview
MAX6023EBT21+T from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference delivering 2.048V output with ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA load current. It operates from 2.5V to 12.6V input and draws only 27–35µA quiescent current, making it ideal for high-accuracy data acquisition systems requiring stable excitation for 12-bit ADCs.
For engineers reviewing the MAX6023EBT21+T datasheet, MAX6023EBT21+T pinout, MAX6023EBT21+T application, or MAX6023EBT21+T equivalent, key selection criteria include guaranteed initial accuracy over temperature, ultra-low supply current variation (≤0.8µA/V), capacitive-load stability up to 2.2nF without external compensation, and UCSP package constraints for space-constrained PCB layouts.
Technical Context
The MAX6023EBT21+T uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift and ±0.2% initial accuracy across –40°C to +85°C. Its series-mode architecture enables sourcing/sinking up to ±500µA while maintaining regulation under 100mV dropout.
Internally compensated for loads up to 2.2nF, it eliminates need for output capacitor-critical in battery-powered systems where board area and component count are constrained. Supply current remains stable (27–35µA) with only 0.8µA/V variation over VIN, directly improving battery life versus shunt-mode alternatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.2% at +25°C - enables precise 12-bit DAC/ADC reference scaling with minimal calibration overhead |
| Initial Accuracy | ±0.2% max - guarantees system-level offset error ≤2.5mV without trimming |
| Tempco | ≤30ppm/°C - limits full-range drift to ±2.5mV over –40°C to +85°C |
| Dropout Voltage | 100mV at 500µA load - supports operation down to 2.148V input in 2.5V rail systems |

Pinout & Package
MAX6023EBT21+T uses a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), optimized for ultra-low profile and minimal PCB footprint. Bump layout follows standard UCSP.EPS top view with bumps on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected on PCB - no routing or soldering allowed |
| A2 | GND | Reference ground return - requires low-impedance connection to system AGND plane |
| B1 | OUT | 2.048V precision reference output - drives ADC REF+, DAC VREF, or sensor excitation |
| B3 | IN | Input supply (2.5V–12.6V) - must be filtered per UCSP thermal reliability guidelines |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable operation with 0–2.2nF load capacitance - eliminates BOM cost and layout area for decoupling cap |
| Ultra-low supply current variation | ≤0.8µA/V over full input range - enables accurate battery-life estimation in energy-harvesting designs |
| Low-profile UCSP packaging | 0.3mm height - fits beneath connectors or in stacked modules where SOT23/SC70 exceed height budget |
| Guaranteed performance over temperature | ±0.2% accuracy and ≤30ppm/°C drift from –40°C to +85°C - qualified for industrial control environments |
| Low dropout at full load | 100mV @ 500µA - permits use with Li-ion batteries down to 2.15V or single-cell alkaline systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3420ARJZ-R7 | 2.048V output, ±0.1% initial accuracy, 30ppm/°C tempco, but 125µA supply current and SOT23-5 package (1.3mm height) | Higher power draw reduces battery life; larger footprint limits ultra-thin designs | Select when tighter initial accuracy justifies higher current and larger package |
| REF3020AIDBZR | 2.048V output, ±0.2% initial accuracy, 50ppm/°C tempco, 40µA supply current, SOT23-3 package | Worse tempco increases full-range drift by ~3×; no IN pin - less flexible input filtering | Select when lowest BOM cost is priority and 50ppm/°C drift is acceptable |

FAQ
What is the maximum load current supported by MAX6023EBT21+T while maintaining regulation?
MAX6023EBT21+T supports ±500µA load current while maintaining regulation within specifications. At 500µA sink or source, dropout voltage remains ≤200mV, and output voltage change is limited to ≤1.4µV/µA load regulation error. This capability enables direct driving of ADC reference inputs, op-amp bias networks, or sensor excitation circuits without external buffering.
Does MAX6023EBT21+T require an external output capacitor for stability?
No, MAX6023EBT21+T does not require an external output capacitor for stability. It is internally compensated and remains oscillation-free with capacitive loads from 0 to 2.2nF. An external capacitor may be added to improve transient response during step-load changes, but it is optional and unnecessary for basic regulation stability.
What is the input voltage range for MAX6023EBT21+T?
MAX6023EBT21+T operates with input voltages from 2.5V to 12.6V. Unlike higher-output variants in the MAX6023 family, the 2.048V version supports the wider 2.5V minimum input across its full operating range - enabling compatibility with 2.5V, 3.3V, and 5V supply rails without requiring boost conversion.
How does the supply current of MAX6023EBT21+T vary with input voltage?
MAX6023EBT21+T exhibits exceptionally stable supply current: 27–35µA over full temperature range, with variation ≤0.8µA/V across 2.5V–12.6V input. This near-constant current draw simplifies power budgeting and maximizes battery life - especially critical in coin-cell or energy-harvesting applications where every nanoamp matters.
Is MAX6023EBT21+T compatible with standard reflow soldering processes?
Yes, MAX6023EBT21+T is compatible with JEDEC J-STD-020A-compliant reflow profiles (IR/VPR and convection), including preheating. Hand soldering and wave soldering are prohibited due to UCSP thermal sensitivity. Peak bump temperature must not exceed +300°C for 10 seconds, and thermal profile adherence is mandatory to ensure long-term reliability.
