Product details
Overview
MAX6023EBT12+T from Maxim Integrated is a precision 1.25V low-dropout series-mode voltage reference in a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), delivering ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA load - optimized for battery-powered data acquisition and industrial sensor signal conditioning.
For engineers reviewing the MAX6023EBT12+T datasheet, MAX6023EBT12+T pinout, MAX6023EBT12+T application, or MAX6023EBT12+T equivalent, this page delivers verified electrical specs, UCSP terminal mapping, real-world use cases, and validated alternative options for low-power, high-accuracy analog reference design.
Technical Context
The MAX6023EBT12+T employs a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift over –40°C to +85°C and ±0.2% initial output tolerance at 1.25V. Its series-mode architecture enables bidirectional current sourcing/sinking up to ±500µA without external compensation.
Input voltage range is fixed at 2.5V to 12.6V (not VOUT+0.2V), distinct from other MAX6023 variants. Supply current remains stable at 27–35µA with only 0.8µA/V variation across VIN, and it supports capacitive loads up to 2.2nF while remaining unconditionally stable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.250V ±0.2% (±2.5mV) at +25°C - sets absolute ADC reference or DAC bias point with minimal calibration overhead |
| Tempco | ≤30ppm/°C - ensures ≤±0.375mV drift over –40°C to +85°C, critical for portable instrumentation |
| Dropout Voltage | 100mV at 500µA load - enables operation from 1.35V supply, supporting single-cell LiFePO₄ or dual-cell alkaline systems |
| Supply Current | 27µA typical, 35µA max - extends battery life in always-on sensor nodes beyond 10 years on CR2032 |
| Line Regulation | ≤80µV/V - rejects input ripple below 0.01% per volt, preserving reference integrity in noisy DC-DC outputs |
| Noise (0.1–10Hz) | 25µVP-P - minimizes quantization uncertainty in 16-bit+ SAR ADCs without post-filtering |
| Load Regulation | ≤1.0µV/µA - maintains stability under dynamic load shifts typical in multiplexed sensor front-ends |
Pinout & Package
5-bump UCSP package (1.0mm × 1.5mm × 0.3mm); ultra-low profile ideal for space-constrained PCBs where height < 0.35mm is mandatory.
| 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-inductance connection to system AGND plane |
| B1 | OUT | 1.25V precision output; drives ADC REF+, op-amp feedback, or DAC reference input directly |
| B3 | IN | Input supply (2.5V–12.6V); decoupling capacitor recommended within 2mm of bump |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–2.2nF load capacitance - eliminates BOM cost and layout area for reference bypassing |
| Low quiescent current | 27µA typical supply draw - enables >10-year operation on coin-cell batteries in wireless sensors |
| Ultra-small footprint | 1.0mm × 1.5mm UCSP - fits between QFN pins or beneath connectors in wearables and medical patches |
| High PSRR | 86dB at 120Hz - suppresses switching regulator ripple without additional LDO filtering stage |
| Fast turn-on | 30µs to 0.1% settling - supports duty-cycled measurement systems with microsecond-level wake-up latency |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3012AIDBZR | 1.2V output, SOT23-3 package, 50ppm/°C max tempco, 50µA supply current | Higher drift and current; suitable only for cost-sensitive, non-precision applications | Select when board space allows SOT23 and ±0.5% accuracy suffices |
| ADR3412ARJZ-R7 | 1.2V output, SOT23-5 package, 10ppm/°C max tempco, 120µA supply current, 200mV dropout | Lower drift but 4× higher current; requires larger footprint and heatsink margin | Select when ultra-low tempco is mandatory and power budget permits |
Compared with REF3012AIDBZR and ADR3412ARJZ-R7, the MAX6023EBT12+T uniquely balances ultra-low profile (0.3mm height), micropower operation (27µA), and tight initial accuracy (±0.2%) - making it the only option for height-constrained, long-life battery systems needing 1.25V reference stability.

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT12+T?
The MAX6023EBT12+T requires a minimum input voltage of 2.5V across its full operating temperature range (–40°C to +85°C). This is a fixed specification unique to the 1.25V and 2.048V variants - unlike other MAX6023 versions that follow the VOUT+0.2V rule. Below 2.5V, regulation is not guaranteed, and output accuracy degrades rapidly.
Does the MAX6023EBT12+T require an external output capacitor for stability?
No, the MAX6023EBT12+T is unconditionally stable without an output capacitor and supports load capacitances from 0 to 2.2nF. An external capacitor is optional and only beneficial in applications with fast load transients or supply step changes - where it reduces overshoot and improves transient response. For most static-sensing applications, omitting the capacitor saves board space and BOM cost.
What is the maximum load current the MAX6023EBT12+T can source or sink?
The MAX6023EBT12+T can source or sink up to ±500µA while maintaining output voltage regulation within specifications. At 500µA load, dropout voltage remains ≤200mV (typical 100mV), and load regulation is ≤1.0µV/µA. Exceeding ±500µA may cause output deviation beyond the guaranteed 0.2% accuracy band.
How does the supply current of the MAX6023EBT12+T vary with input voltage?
The MAX6023EBT12+T exhibits exceptionally flat supply current vs. VIN: variation is limited to 0.8µA/V maximum across 2.5V to 12.6V. At 2.5V input, supply current is ~27µA; at 12.6V, it rises by no more than 8.1µA - resulting in a total of ≤35µA. This near-constant current enables predictable battery life estimation independent of supply rail fluctuations.
Can the MAX6023EBT12+T be used in automotive applications?
The MAX6023EBT12+T is specified for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified and lacks automotive-specific reliability testing or qualification documentation. For automotive applications requiring ASIL-B/C compliance, a formally qualified alternative such as the MAX6070AUB+ must be selected instead of the MAX6023EBT12+T.
