Product details
Overview
MAX6023EBT50 from Maxim Integrated is a 5.0V, low-dropout, micropower 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 precision analog sensing and battery-powered data acquisition systems.
For engineers reviewing the MAX6023EBT50 datasheet, MAX6023EBT50 pinout, MAX6023EBT50 application, or MAX6023EBT50 equivalent, this page provides verified electrical specs, UCSP bump mapping, thermal stability data, load-transient response characteristics, and validated alternative options for low-power, high-accuracy reference design.
Technical Context
The MAX6023EBT50 uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift over –40°C to +85°C and ±0.2% initial output tolerance at 5.000V. It operates as a three-terminal series-mode reference requiring only VIN ≥ 5.2V (VOUT + 0.2V) up to 12.6V.
Its internal compensation eliminates need for external capacitors, and it remains stable with 0–2.2nF load capacitance. Supply current is tightly regulated at 27–35µA with only 0.9µA/V variation across input voltage - enabling predictable power budgeting in energy-constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.2% at +25°C - ensures ADC/DAC reference accuracy within 10mV absolute error without calibration. |
| Tempco | ≤30ppm/°C - limits full-range drift to ≤15mV over –40°C to +85°C, critical for industrial sensor front-ends. |
| Dropout Voltage | 100–200mV at 500µA - enables operation from 5.2V supply in 5V-rail systems with minimal headroom loss. |
| Quiescent Current | 27–35µA - supports >1-year battery life in coin-cell–powered instrumentation with 10µA sleep modes. |
| Line Regulation | ≤160µV/V - suppresses supply ripple-induced errors below 0.8 LSB in 16-bit SAR ADC references. |
| Load Regulation | ≤2.2µV/µA - maintains <11µV shift across full 500µA sourcing/sinking range, preserving precision under dynamic loads. |
| Noise (10Hz–10kHz) | 240µVRMS - contributes <0.004% of full-scale error in 5V-referenced 16-bit converters. |
Pinout & Package
MAX6023EBT50 uses a 5-bump wafer-level chip-scale package (UCSP-5), measuring 1.0mm × 1.5mm × 0.3mm - the lowest-profile surface-mount voltage reference available, ideal for ultra-thin portable medical sensors and space-constrained IoT modules.
| 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 AGND plane to minimize noise coupling. |
| B1 | OUT | 5.0V precision reference output - directly drives ADC REF pins or op-amp non-inverting inputs without buffering. |
| B3 | IN | Input supply terminal - accepts 5.2V–12.6V; must be decoupled with ≥1µF ceramic capacitor near bump for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–2.2nF load capacitance - eliminates BOM cost and board area for decoupling caps in compact designs. |
| Low dropout at full load | 100mV dropout at 500µA - allows use with LDOs or DC-DC outputs as low as 5.2V, reducing system power loss. |
| Supply-current stability | 0.9µA/V variation - enables accurate battery-life estimation and eliminates supply-voltage–dependent offset drift. |
| UCSP footprint | 1.5mm² area, 0.3mm height - fits beneath 0402 passives and enables placement directly adjacent to ADC die for minimal trace inductance. |
| Turn-on settling time | 220µs to 0.1% - meets timing requirements for fast-sampling data loggers without delaying first valid conversion. |

FAQ
What is the minimum input voltage required for stable operation of the MAX6023EBT50?
The MAX6023EBT50 requires a minimum input voltage of VOUT + 0.2V = 5.2V for guaranteed specification compliance across temperature and load. Operation below 5.2V may cause output deviation exceeding ±0.2% or increased dropout - the MAX6023EBT50 datasheet specifies 5.2V as the absolute lower limit for full performance.
Can the MAX6023EBT50 drive a 2.2nF capacitive load without oscillation?
Yes, the MAX6023EBT50 is internally compensated and specified stable with load capacitances from 0 to 2.2nF - confirmed in the Electrical Characteristics table and Typical Operating Characteristics (Figure toc09). This eliminates need for external compensation and supports direct connection to ADC input capacitors or long PCB traces.
How does the supply current of the MAX6023EBT50 vary with input voltage?
The MAX6023EBT50 exhibits a maximum supply current variation of 0.9µA/V across its input range (5.2V to 12.6V), meaning total change is ≤6.8µA over full VIN span. This tight regulation enables precise battery-life modeling - the MAX6023EBT50 draws 27–35µA regardless of VIN, unlike shunt references whose current scales with load.
Is the MAX6023EBT50 suitable for automotive applications?
The MAX6023EBT50 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 use, consider the MAX6023EBT50 only in cabin-infotainment or body-control modules where ambient temperature stays within its extended industrial range.
What is the turn-on settling time specification for the MAX6023EBT50?
The MAX6023EBT50 settles to within 0.1% of final 5.0V output in 220µs with COUT = 50pF, as measured in the Electrical Characteristics table (page 8). This value increases under worst-case conditions (minimum dropout, max load), but remains ≤1.5ms - the MAX6023EBT50 datasheet guarantees 220µs as typical turn-on time for standard conditions.
