Product details
Overview
MAX6033BAUT50+T from Maxim Integrated is a high-precision, low-dropout series voltage reference delivering a stable 5.000V output with ±0.20% initial accuracy, 15ppm/°C max temperature coefficient over -40°C to +125°C, and 40µA quiescent current. It serves as a precision DC bias source in high-resolution data converters and industrial control systems requiring tight regulation under varying load and temperature.
For engineers reviewing the MAX6033BAUT50+T datasheet, MAX6033BAUT50+T pinout, MAX6033BAUT50+T application, or MAX6033BAUT50+T equivalent, key selection criteria include dropout voltage at 10mA (≤400mV), load regulation (≤0.1mV/mA over full temp range), stability with up to 100µF capacitive loads, and automotive-grade operating temperature support.
Technical Context
The MAX6033BAUT50+T employs bandgap-based architecture with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.20% initial accuracy and 15ppm/°C max TCVOUT across -40°C to +125°C. Its dual-output force-sense topology (OUTF/OUTS) enables precise remote sensing and eliminates errors from trace resistance.
As a series-mode reference, it draws only 40µA supply current independent of input voltage and sources up to 15mA while maintaining low noise (40µVP-P, 0.1Hz–10Hz) and fast turn-on settling (1000µs to ±0.01%). Input voltage range is 5.2V to 12.6V for 5V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.20% at +25°C - ensures direct compatibility with 5V ADC/DAC reference inputs without calibration. |
| Temp Coefficient | 15ppm/°C max (-40°C to +125°C) - limits drift to ≤750ppm over full automotive range, critical for uncalibrated precision systems. |
| Dropout Voltage | 400mV max at 10mA and +125°C - enables operation from 5.4V supply in thermally stressed environments. |
| Load Regulation | 0.2mV/mA max (-40°C to +125°C) - maintains <0.004% output change per mA load shift, essential for dynamic current-sourcing applications. |
| Quiescent Current | 40µA typical at +25°C - reduces system power by >90% vs. shunt references, extending battery life in portable instrumentation. |
| Noise (0.1–10Hz) | 40µVP-P - contributes <0.0008% RMS error to 5V full-scale, preserving ENOB in 16-bit+ converters. |
| Capacitive Load Stability | Stable with 0.1µF to 100µF - supports robust filtering without oscillation, simplifying layout in noisy industrial settings. |
Pinout & Package
MAX6033BAUT50+T is housed in a RoHS-compliant 6-pin SOT23 package (U6FH+6 outline) with thermal resistance θJA = 134.4°C/W on four-layer board, enabling compact placement in space-constrained automotive and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | Not externally usable; internal connection only - must remain unconnected to avoid parasitic coupling or damage. |
| 2 | GND | Analog ground reference for internal bandgap core - requires low-impedance connection to system AGND plane. |
| 4 | IN | Positive supply input (5.2V–12.6V) - must be decoupled with ≥0.1µF ceramic capacitor placed adjacent to pin. |
| 5 | OUTF | Force output driving external load - connects directly to load or sense resistor; bypassed to GND with ≥0.1µF capacitor. |
| 6 | OUTS | Sense input monitoring feedback point - tied to OUTF near device to cancel PCB trace IR drop and maintain accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output force-sense topology | Eliminates voltage drop error from PCB traces and interconnects, preserving ±0.20% accuracy under real-world layout conditions. |
| Automotive temperature range | Guaranteed operation from -40°C to +125°C - qualified for engine control units, ADAS sensors, and under-hood power management. |
| Laser-trimmed thin-film resistors | Enables ±0.20% initial accuracy without external calibration, reducing test time and BOM cost in high-volume production. |
| Low-noise bandgap core | 40µVP-P (0.1–10Hz) noise floor - prevents degradation of signal-to-noise ratio in precision analog front-ends. |
| Stable with large capacitive loads | Operates reliably with 100µF output capacitance - allows use of bulk electrolytic + ceramic combos for ripple suppression in power-sensitive designs. |
Applications
| Industrial Process Monitoring | Automotive Engine Control Unit (ECU) |

FAQ
What is the maximum load current supported by the MAX6033BAUT50+T?
The MAX6033BAUT50+T sources up to 15mA while maintaining specified accuracy and dropout voltage. At 10mA and +125°C, dropout remains ≤400mV, and load regulation stays within 0.2mV/mA. Exceeding 15mA risks output voltage deviation beyond guaranteed limits and potential thermal stress.
Can the MAX6033BAUT50+T operate with a 5.2V input supply?
Yes - the MAX6033BAUT50+T has a minimum input voltage of 5.2V for 5.000V output, as specified in its Electrical Characteristics table. At this rail, dropout is 200mV (typical) and 400mV (max at 10mA/+125°C), ensuring reliable regulation with margin for line variation and PCB drop.
How does the OUTF/OUTS pin configuration improve accuracy in the MAX6033BAUT50+T?
The MAX6033BAUT50+T uses separate force (OUTF) and sense (OUTS) outputs to eliminate voltage error caused by current flowing through PCB traces or interconnects. By routing OUTS directly to the load's reference point and tying it to OUTF near the IC, the device regulates voltage precisely at the load, not at the pin - preserving ±0.20% accuracy despite trace resistance.
Is the MAX6033BAUT50+T suitable for automotive applications?
Yes - the MAX6033BAUT50+T is explicitly rated for the automotive temperature range (-40°C to +125°C) and features guaranteed parameters across that span, including 15ppm/°C max tempco and 400mV max dropout at +125°C. Its RoHS-compliant SOT23-6 package meets AEC-Q200 stress test expectations for passive components.
What output capacitor value is required for stability with the MAX6033BAUT50+T?
The MAX6033BAUT50+T requires a minimum 0.1µF ceramic capacitor on the OUTF pin to GND for stability and optimal transient response. It remains stable with output capacitance up to 100µF, allowing designers to combine ceramic and bulk electrolytic capacitors for enhanced ripple rejection without risk of oscillation.
