Product details
Overview
MAX6033CAUT50#G16 from Maxim Integrated is a high-precision, low-dropout series voltage reference delivering 5.000V output with ±0.1% initial accuracy, 40ppm/°C max temperature coefficient, and 40µA quiescent current. It operates from 5.2V to 12.6V input, supports 15mA source current, and targets high-resolution ADC/DAC biasing in automotive-grade industrial systems.
For engineers reviewing the MAX6033CAUT50#G16 datasheet, MAX6033CAUT50#G16 pinout, MAX6033CAUT50#G16 application, or MAX6033CAUT50#G16 equivalent, this page delivers verified electrical parameters, SOT23-6 terminal mapping, automotive temperature range (-40°C to +125°C) validation, and real-world use cases for precision analog signal chains.
Technical Context
The MAX6033CAUT50#G16 uses bandgap-based architecture with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.1% initial accuracy and 40ppm/°C tempco over -40°C to +125°C. Its dual-output (OUTF/OUTS) Kelvin-sensing topology eliminates lead resistance error in precision load regulation.
This device functions as a 3-terminal series reference: IN supplies power, GND establishes reference ground, and the force-sense pair (OUTF/OUTS) maintains stable 5.000V output under varying load and PCB trace impedance. Dropout voltage remains ≤400mV at 10mA load across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.1% at +25°C - guarantees absolute reference level for 14-bit+ DACs without calibration. |
| Tempco | 40ppm/°C max (−40°C to +125°C) - limits drift to ±0.5mV over full automotive range. |
| Dropout Voltage | 400mV max at 10mA - enables operation from 5.4V supply in battery-powered systems. |
| Quiescent Current | 40µA typical - reduces standby power in always-on sensor nodes and portable instruments. |
| Noise (0.1–10Hz) | 40µVP-P - preserves SNR in 16-bit+ data acquisition front-ends. |
| Load Regulation | 0.2mV/mA max - ensures <0.004% output shift per mA load change for stable ADC reference. |
| Line Regulation | 100µV/V max - rejects supply ripple up to 12.6V without external filtering. |
Pinout & Package
MAX6033CAUT50#G16 is housed in a RoHS-compliant 6-pin SOT23 package (outline 21-0058), with 1.6mm × 2.9mm footprint and 0.95mm height. Pin 1 and Pin 3 are internally connected and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | No external connection required; internal bond wire only - avoid routing or soldering. |
| 2 | GND | Analog ground reference plane - connect directly to low-impedance ground pour beneath device. |
| 4 | IN | Positive supply input - decouple with ≥0.1µF ceramic capacitor placed adjacent to pin. |
| 5 | OUTF | Force output - drives load current; bypass with 0.1µF cap to GND for transient stability. |
| 6 | OUTS | Sense input - connects to load-side of reference resistor to eliminate trace IR drop error. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.000V output, ±0.02% initial accuracy, 3ppm/°C tempco, 950µA quiescent current | Higher accuracy and lower drift, but 23× higher supply current - unsuitable for battery operation | Select ADR4550BRZ only when ultra-low tempco dominates over power budget constraints. |
| REF5050AIDR | 5.000V output, ±0.05% initial accuracy, 3ppm/°C tempco, 950µA quiescent current, SOIC-8 package | Superior long-term stability (15ppm/1000hr vs. 40ppm), but larger footprint and higher power - incompatible with space-constrained designs | Choose REF5050AIDR for lab-grade instrumentation where size and power are secondary to drift performance. |
Compared with ADR4550BRZ and REF5050AIDR, MAX6033CAUT50#G16 uniquely balances automotive-grade temperature range, ultra-low 40µA quiescent current, and SOT23-6 miniaturization - making it the only viable option for cost-sensitive, battery-powered, or space-constrained automotive and industrial applications requiring 5V precision reference.

FAQ
What is the maximum load current supported by MAX6033CAUT50#G16?
MAX6033CAUT50#G16 sources up to 15mA while maintaining specified accuracy and dropout voltage. At 10mA load and −40°C to +125°C, dropout remains ≤400mV and output voltage deviation stays within ±0.1% of 5.000V. Exceeding 15mA may cause thermal shutdown or irreversible accuracy degradation.
Does MAX6033CAUT50#G16 require an input capacitor?
MAX6033CAUT50#G16 does not require an input capacitor for basic operation, but a 0.1µF ceramic capacitor placed adjacent to the IN pin is recommended for optimal line-transient response. This capacitor reduces input ripple coupling into the reference output, especially critical in noisy automotive or industrial power environments.
How does the OUTF/OUTS pin configuration improve accuracy in MAX6033CAUT50#G16?
The OUTF/OUTS Kelvin connection in MAX6033CAUT50#G16 separates current delivery (OUTF) from voltage sensing (OUTS), eliminating errors caused by voltage drop across PCB traces or bonding wires. When OUTS is connected directly to the load, MAX6033CAUT50#G16 regulates the sensed point to exactly 5.000V - enabling <0.001% load regulation even with 100mΩ trace resistance.
Is MAX6033CAUT50#G16 qualified for automotive applications?
Yes, MAX6033CAUT50#G16 is explicitly rated for the automotive temperature range (−40°C to +125°C) and packaged in RoHS-compliant SOT23-6. Its 40ppm/°C max tempco, 150ppm temperature hysteresis, and 40ppm/1000hr long-term stability meet AEC-Q100 stress test requirements for non-automotive-specific qualification - widely deployed in engine control units and ADAS sensor interfaces.
What is the minimum input voltage required for MAX6033CAUT50#G16 to regulate at 5.000V?
The minimum input voltage for MAX6033CAUT50#G16 is 5.4V - calculated as 5.000V + 400mV max dropout at 10mA load. Below 5.4V, output voltage drops linearly with input; regulation is guaranteed only when VIN ≥ (VOUT + VDO). For reliable start-up, the supply must deliver up to 150µA transient current during turn-on before settling to 40µA quiescent draw.
