Product details
Overview
MAX6033CAUT30#TG16 from Maxim Integrated is a high-precision, low-dropout series voltage reference delivering 3.000V output with ±0.10% initial accuracy, 40ppm/°C max temperature coefficient (−40°C to +125°C), and 40µA quiescent current. It features dual-output force/sense architecture (OUTF/OUTS) for improved load regulation and is optimized for high-resolution ADC/DAC biasing in automotive-grade instrumentation.
For engineers reviewing the MAX6033CAUT30#TG16 datasheet, MAX6033CAUT30#TG16 pinout, MAX6033CAUT30#TG16 application, or MAX6033CAUT30#TG16 equivalent, key selection criteria include its 3.0V output stability under capacitive loads up to 100µF, 0.002mV/mA load regulation at +25°C, and guaranteed operation across −40°C to +125°C without external compensation.
Technical Context
The MAX6033CAUT30#TG16 implements a bandgap-based series reference with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.10% initial accuracy and 40ppm/°C tempco over the full automotive range. Its dual-terminal OUTF/OUTS configuration enables remote sensing to reject PCB trace resistance effects.
It operates from 3.2V to 12.6V input, maintains 0.2V max dropout at 1mA load, and delivers 15mA source capability while consuming only 40µA typical supply current - enabling efficient single-supply biasing of precision data converters in battery-sensitive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.003V at +25°C - ensures stable reference for 14-bit+ DACs requiring ≤0.5LSB error. |
| Initial Accuracy | ±0.10% - eliminates need for system-level calibration in industrial sensor front-ends. |
| Temp Coefficient | 40ppm/°C max (−40°C to +125°C) - supports AEC-Q100 Grade 1 compliance for automotive control modules. |
| Quiescent Current | 40µA typical - extends battery life in portable test equipment and handheld meters. |
| Dropout Voltage | 0.2V max at 1mA - allows operation from 3.3V rails with ≥0.3V headroom, simplifying LDO selection. |

Pinout & Package
MAX6033CAUT30#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline, land pattern 90-0175) with exposed pad thermal enhancement. Pins 1 and 3 are internally connected and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2 GND | Ground Reference | Low-impedance return path for reference core and sense circuitry; requires solid plane connection. |
| 4 IN | Positive Supply Input | Accepts 3.2–12.6V; bypass with ≥0.1µF ceramic capacitor placed adjacent to pin for transient immunity. |
| 5 OUTF | Force Output | Delivers regulated 3.0V; connects directly to load and to OUTS via shortest possible trace to enable Kelvin sensing. |
| 6 OUTS | Sense Input | Feedback node for internal error amplifier; rejects voltage drop across PCB traces between OUTF and load. |

FAQ
What is the maximum capacitive load supported by MAX6033CAUT30#TG16 without instability?
MAX6033CAUT30#TG16 is stable with output capacitance ranging from 0.1µF to 100µF, including ceramic, tantalum, and polymer types. This wide range allows designers to select bulk capacitance for hold-up time or low-ESR ceramics for transient response without requiring external compensation networks - a key advantage over many competing references that oscillate above 10µF.
Does MAX6033CAUT30#TG16 require an input bypass capacitor?
While not strictly mandatory, MAX6033CAUT30#TG16 achieves optimal line-transient performance with a 0.1µF ceramic capacitor placed as close as possible to the IN pin. Without it, PSRR degrades above 1kHz, increasing susceptibility to supply ripple - especially critical in shared-rail systems powering both digital controllers and precision analog stages.
How does the OUTF/OUTS pin configuration improve accuracy in MAX6033CAUT30#TG16?
In MAX6033CAUT30#TG16, OUTF delivers the regulated 3.0V to the load while OUTS senses voltage directly at the load point. This Kelvin connection cancels voltage drop across PCB traces and connectors, reducing load-regulation error from typical 0.1mV/mA to just 0.002mV/mA - enabling sub-0.01% accuracy even with 100mm trace lengths.
What is the minimum input voltage required for MAX6033CAUT30#TG16 to maintain regulation at full load?
At 15mA load and +125°C, MAX6033CAUT30#TG16 requires VIN ≥ 3.5V to maintain regulation (3.0V + 0.5V dropout). At room temperature and 1mA load, dropout drops to 0.2V, allowing operation from 3.2V supplies - making it compatible with standard 3.3V LDO outputs while preserving margin for rail sag.
Is MAX6033CAUT30#TG16 qualified for automotive applications?
Yes, MAX6033CAUT30#TG16 is specified for −40°C to +125°C operation and manufactured in an automotive-qualified process. While not formally AEC-Q200 certified as a discrete component, its electrical specifications, packaging (RoHS-compliant SOT23), and qualification testing align with AEC-Q100 Grade 1 requirements for passive and active components used in engine control, body electronics, and ADAS subsystems.
