Product details
Overview
MAX6023EBT50-T from Maxim Integrated is a precision 5.0V 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 - ideal for high-accuracy ADC/DAC biasing in portable instrumentation and battery-powered data acquisition systems.
For engineers reviewing the MAX6023EBT50-T datasheet, MAX6023EBT50-T pinout, MAX6023EBT50-T application, or MAX6023EBT50-T equivalent, key selection criteria include its 5.0V output stability over -40°C to +85°C, ultra-low 35µA quiescent current, 2.2nF capacitive-load tolerance without external compensation, and UCSP footprint constraints for space-constrained PCB layouts.
Technical Context
The MAX6023EBT50-T uses a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift and ±0.2% initial accuracy across -40°C to +85°C. It operates as a three-terminal series-mode reference requiring VIN ≥ (VOUT + 0.2V) up to 12.6V, enabling use in low-headroom systems where input margins are tight.
Its supply current remains stable at 27–35µA with only 0.9µA/V variation over input voltage, eliminating wasteful constant-current draw typical of shunt references. Internally compensated design supports 0–2.2nF load capacitance without oscillation, simplifying layout in noise-sensitive analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.2% at +25°C - enables direct interface with 5V ADC reference inputs without scaling. |
| Temperature Coefficient | ≤30ppm/°C - ensures ≤1.5mV total drift over -40°C to +85°C for stable sensor signal conditioning. |
| Dropout Voltage | 100mV at 500µA load - allows operation from 5.1V supply in battery-powered systems near end-of-life. |
| Quiescent Current | 27–35µA - extends coin-cell battery life beyond 10 years in always-on monitoring applications. |
| Line Regulation | ≤160µV/V - limits output change to <800µV over 5.1V–12.6V input range, critical for unregulated power rails. |
| Load Regulation | ≤2.2µV/µA - maintains <1.1mV shift from 0 to 500µA load, supporting precision current-sense amplifier biasing. |
| Noise (0.1–10Hz) | 120µVP-P - low enough for 16-bit+ SAR ADC reference without additional filtering. |
Pinout & Package
MAX6023EBT50-T uses a 5-bump wafer-level chip-scale package (UCSP) measuring 1.0mm × 1.5mm × 0.3mm, optimized for minimal board area and height-critical applications such as handheld medical devices and wearables.
| 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 path - requires low-impedance connection to system analog ground plane. |
| B1 | OUT | Stable 5.0V reference output - directly drives ADC REF pins or op-amp bias networks; tolerates 0–2.2nF load capacitance. |
| B3 | IN | Input voltage supply - must be ≥5.2V (VOUT + 0.2V); decoupling capacitor recommended within 2mm of bump. |
Key Features
| Feature | Design Value |
|---|---|
| No external compensation capacitor | Internally compensated for 0–2.2nF load capacitance - eliminates BOM cost and layout area for stability components. |
| Low-profile UCSP package | 0.3mm height - enables placement under connectors or in stacked PCB assemblies where SOT23/SC70 would cause mechanical interference. |
| Supply current stability | 0.9µA/V variation with VIN - ensures predictable battery drain across full operating voltage range, simplifying power budgeting. |
| Turn-on settling time | 220µs to 0.1% final value - supports fast wake-up sequences in duty-cycled sensor nodes without reference stabilization delays. |
| Short-circuit protection | 10mA short-to-GND or short-to-IN current limit - prevents latch-up during ESD events or accidental probe shorts during test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDBVT | SO-8 package (2.9mm × 1.6mm), 50ppm/°C max drift, 50µA supply current, requires 1µF output capacitor. | Higher profile and larger footprint; better suited for industrial boards with ample space and higher noise immunity requirements. | Select when board-level vibration resistance or legacy SO-8 assembly infrastructure is prioritized over size/power. |
| ADR3450ARJZ-R7 | SOT-23-5 package, 10ppm/°C max drift, 45µA supply current, 150mV dropout at 500µA, 1.2µF min output capacitance. | Superior temperature stability but higher dropout and mandatory external capacitor increase solution size and complexity. | Choose for metrology-grade accuracy where 10ppm/°C drift outweighs UCSP size advantage and capacitor-free operation. |
Compared with REF5050IDBVT and ADR3450ARJZ-R7, MAX6023EBT50-T offers the smallest footprint (1.0mm × 1.5mm), lowest quiescent current (27µA), and capacitor-free operation - making it optimal for miniaturized, battery-constrained designs where moderate (30ppm/°C) drift is acceptable.

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT50-T?
The MAX6023EBT50-T requires a minimum input voltage of VOUT + 0.2V = 5.2V for guaranteed specifications. Operation below this threshold may result in increased dropout, reduced line regulation, or failure to maintain output accuracy. The device supports input voltages up to 12.6V, making it compatible with standard 5.5V, 6V, or 12V supply rails when properly decoupled.
Does the MAX6023EBT50-T require an external output capacitor for stability?
No, the MAX6023EBT50-T is internally compensated and remains stable with 0–2.2nF of load capacitance - no external capacitor is required. This eliminates BOM cost and PCB area typically needed for shunt or older series references. An optional capacitor can improve transient response in high-dynamic-load applications but is not necessary for basic stability.
How does the supply current of the MAX6023EBT50-T vary with input voltage?
The MAX6023EBT50-T exhibits only 0.9µA/V variation in supply current across its input voltage range (5.2V to 12.6V), maintaining 27–35µA total consumption. This near-constant current draw - unlike shunt references that waste current regardless of load - maximizes battery efficiency and simplifies power budgeting in portable systems using the MAX6023EBT50-T.
What is the maximum load current the MAX6023EBT50-T can source or sink?
The MAX6023EBT50-T is specified to source or sink up to ±500µA while maintaining output accuracy within datasheet limits. At 500µA load, dropout remains ≤200mV, and load regulation is ≤2.2µV/µA. Exceeding ±500µA may degrade accuracy or cause output deviation beyond the ±0.2% initial tolerance, so design margins should respect this absolute maximum rating.
Can the MAX6023EBT50-T be used in automotive applications?
The MAX6023EBT50-T is rated for -40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified or specified for automotive under-hood environments. For automotive cabin or infotainment applications within its temperature range, validation of board-level reliability (especially UCSP solder joint integrity under thermal cycling) is required before deployment. The MAX6023EBT50-T is not recommended for engine control or safety-critical systems.
