Product details
Overview
MAX6023EBT45-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 4.500V output with ±0.20% initial accuracy and ≤30ppm/°C temperature coefficient over –40°C to +85°C. It operates from (VOUT + 0.2V) to 12.6V input, draws only 35µA max quiescent current, and maintains stability with up to 2.2nF capacitive load - ideal for high-accuracy ADC/DAC biasing in space-constrained portable instrumentation.
For engineers reviewing the MAX6023EBT45-T datasheet, MAX6023EBT45-T pinout, MAX6023EBT45-T application, or MAX6023EBT45-T equivalent, this page delivers verified electrical specs, UCSP bump mapping, real-world load/line regulation behavior, thermal drift performance, and validated alternative options for battery-powered and industrial sensing systems.
Technical Context
The MAX6023EBT45-T uses a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift and ±0.20% initial accuracy across its full operating temperature range. Its series-mode architecture enables active sourcing/sinking of ±500µA while maintaining dropout voltage ≤200mV at 500µA load.
Unlike shunt references, it exhibits minimal supply current variation (≤0.8µA/V) with input voltage changes and requires no external compensation capacitor. Stability is guaranteed from 0 to 2.2nF load capacitance, supporting direct interface with SAR ADCs, precision op-amp references, and low-noise sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.500V ±0.20% (±9mV) at +25°C - ensures accurate full-scale calibration for 12-bit+ data converters |
| Temperature Coefficient | ≤30ppm/°C - contributes ≤±1.26mV drift over –40°C to +85°C, critical for uncalibrated field operation |
| Dropout Voltage | ≤200mV at 500µA load - enables operation from 4.7V rails, supporting single-cell Li-ion or 5V USB-supplied systems |
| Quiescent Supply Current | ≤35µA - extends battery life in always-on monitoring nodes; current varies only 0.8µA per volt of VIN change |
| Load Regulation | ≤2.0µV/µA (–500µA to 0) - holds output within ±1mV under full sink load, preserving reference integrity during dynamic sensor excitation |
| Line Regulation | ≤160µV/V - limits output shift to ≤144µV over 4.7V–12.6V input range, reducing need for upstream LDO filtering |
| Noise (10Hz–10kHz) | 215µVRMS - compatible with 16-bit SAR ADCs requiring <1LSB noise contribution at 4.5V full scale |
Pinout & Package
MAX6023EBT45-T uses a 5-bump wafer-level chip-scale package (UCSP-5) measuring 1.0mm × 1.5mm × 0.3mm, optimized for ultra-low profile and minimal PCB footprint in height-sensitive applications such as wearable medical sensors and stacked-module designs.
| 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 return - requires low-impedance connection to system analog ground plane for optimal PSRR and noise rejection |
| B1 | OUT | Stable 4.500V reference output - directly drives ADC REF pins, DAC reference inputs, or op-amp non-inverting inputs without buffering |
| B3 | IN | Input voltage supply - accepts 4.7V–12.6V; must be decoupled locally with ≥100nF ceramic capacitor to suppress line transients |
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 in compact PCBs |
| Low dropout at full load | ≤200mV dropout at ±500µA - supports rail-to-rail operation in 5V systems with minimal headroom loss |
| Supply current stability | ≤0.8µA/V VIN sensitivity - prevents reference error drift due to input rail sag in battery-discharge scenarios |
| High PSRR | ≥77dB at 120Hz - rejects ripple from switching regulators or noisy DC/DC outputs feeding the IN pin |
| Turn-on settling time | 85µs to 0.1% of final value (COUT = 50pF) - enables fast wake-up in duty-cycled measurement systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3445ARJZ-R7 | 4.5V output, ±0.12% initial accuracy, 3 ppm/°C typical drift, SOT-23-5 package (2.9mm × 1.6mm) | Larger footprint and higher cost; superior drift spec but less suitable for ultra-compact layouts | Select when long-term stability (<15ppm/1000hr) and lower drift outweigh size constraints |
| REF3345AIDBVR | 4.5V output, ±0.2% initial accuracy, 50ppm/°C max drift, SOT-23-3 package (2.9mm × 1.6mm) | Higher temperature coefficient; lacks guaranteed 2.2nF capacitive-load stability; lower PSRR (65dB) | Select for cost-sensitive, non-temperature-critical applications where UCSP assembly complexity is prohibitive |
Compared with ADR3445ARJZ-R7, MAX6023EBT45-T offers 45% smaller PCB area and lower profile but trades 20ppm/°C higher worst-case drift; versus REF3345AIDBVR, it delivers 2× better thermal stability and proven 2.2nF load tolerance at identical accuracy and price tier.

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT45-T?
The MAX6023EBT45-T requires a minimum input voltage of (VOUT + 0.2V) = 4.7V for guaranteed specification compliance across –40°C to +85°C. Below this, dropout behavior increases and output accuracy degrades. At 500µA load, dropout voltage remains ≤200mV, so operation down to 4.7V is fully supported. The device may function at lower VIN but without parametric guarantees.
Does the MAX6023EBT45-T require an external output capacitor for stability?
No, the MAX6023EBT45-T is internally compensated and stable with 0–2.2nF capacitive load - no external output capacitor is required. Adding one (e.g., 100pF–1nF) can improve transient response to step load changes but introduces no stability risk. This eliminates BOM cost and saves PCB area in space-critical designs using the MAX6023EBT45-T.
How does supply current vary with input voltage for the MAX6023EBT45-T?
The MAX6023EBT45-T exhibits ≤0.8µA/V variation in supply current across its input range (4.7V–12.6V), with a maximum quiescent current of 35µA. This near-constant current draw - unlike shunt references that waste current - maximizes battery life and simplifies power budgeting in systems powered by varying sources like USB or aging batteries.
Can the MAX6023EBT45-T drive a 500µA load while maintaining specified accuracy?
Yes, the MAX6023EBT45-T is rated to source and sink ±500µA while maintaining ≤200mV dropout and ≤2.0µV/µA load regulation. At full 500µA sink, output deviation remains within ±1mV of nominal 4.500V - well within its ±9mV initial accuracy window. This makes the MAX6023EBT45-T suitable for driving ADC reference inputs, op-amp bias networks, and sensor excitation circuits.
What is the thermal hysteresis performance of the MAX6023EBT45-T?
The MAX6023EBT45-T has a guaranteed maximum temperature hysteresis of 90ppm - defined as the output voltage change at +25°C before and after cycling between –40°C and +85°C. This translates to ≤±0.405mV shift in the 4.500V output, ensuring repeatable calibration stability in systems undergoing repeated thermal cycles, such as outdoor environmental monitors or automotive ECUs.
