Product details
Overview
MAX6033CAUT50#TG16 from Maxim Integrated is a high-precision, low-dropout series voltage reference delivering a stable 5.000V output with ±0.10% initial accuracy and 40ppm/°C max temperature coefficient over -40°C to +125°C. It features 200mV max dropout at 10mA load, 40µA quiescent current, and 40µVP-P (0.1Hz–10Hz) output noise - optimized for high-resolution ADCs, DACs, and automotive-grade precision power supplies.
For engineers reviewing the MAX6033CAUT50#TG16 datasheet, MAX6033CAUT50#TG16 pinout, MAX6033CAUT50#TG16 application, or MAX6033CAUT50#TG16 equivalent, this page provides verified technical context, validated pin functions, real-world application cards, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX6033CAUT50#TG16 uses bandgap-based series architecture 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-output force-sense topology (OUTF/OUTS) enables precise regulation under varying load and PCB trace impedance conditions.
It operates from 5.2V to 12.6V input, delivers up to 15mA output current, and maintains stability with capacitive loads from 0.1µF to 100µF. Load regulation is specified at 0.003–0.2 mV/mA across temperature, and line regulation is ≤100 µV/V over its input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.005V at +25°C - ensures direct compatibility with 5V-rail ADC references and industrial logic interfaces. |
| Initial Accuracy | ±0.10% - translates to ±5mV absolute error, enabling single-supply 14-bit DAC systems without calibration. |
| Temp Coefficient | 40ppm/°C max (−40°C to +125°C) - supports automotive under-hood applications where ambient drift must stay below 200ppm over full range. |
| Dropout Voltage | 0.2V max at 1mA, 0.4V max at 10mA - allows operation from 5.2V supply while maintaining regulation in low-headroom systems. |
| Quiescent Current | 40µA typical - enables multi-year battery life in portable instrumentation with minimal standby power penalty. |
| Output Noise | 40µVP-P (0.1Hz–10Hz), 26µVRMS (10Hz–1kHz) - preserves ENOB >16 bits in 20ksps precision data acquisition. |
| Load Regulation | 0.003 mV/mA typ, 0.2 mV/mA max - minimizes output shift during dynamic sensor excitation or DAC settling transients. |
Pinout & Package
MAX6033CAUT50#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (package code U6F+6), with exposed pad not electrically connected. The device uses a force-sense output architecture requiring tight layout coupling between OUTF and OUTS pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | No external connection required; internal tie-off only - floating or routing causes no functional impact. |
| 2 | GND | Analog ground reference for internal bandgap core; must connect to low-noise system ground plane. |
| 4 | IN | Positive supply input (5.2V–12.6V); requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin. |
| 5 | OUTF | Force output - drives load current; must be shorted to OUTS within 1mm on PCB for accurate sensing. |
| 6 | OUTS | Sense input - monitors regulated voltage at load; feedback path determines final output accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output architecture | Compensates for PCB trace resistance and load-induced IR drop - maintains ±0.10% accuracy at remote point-of-load. |
| Stable with 0.1µF–100µF capacitive loads | Eliminates need for external compensation networks and supports wide-range decoupling strategies in mixed-signal systems. |
| Ultra-low 40µA quiescent current | Reduces total system standby power by >95% vs. legacy shunt references - critical for always-on automotive sensors. |
| Automotive temperature range | Qualified from −40°C to +125°C - meets AEC-Q100 stress test requirements for engine control and ADAS subsystems. |
| Low 150ppm temperature hysteresis | Ensures repeatable voltage after thermal cycling - essential for factory-calibrated test equipment and metrology instruments. |

FAQ
What is the maximum load current supported by MAX6033CAUT50#TG16?
MAX6033CAUT50#TG16 sources up to 15mA output current while maintaining regulation and specified accuracy. At 10mA load and −40°C to +125°C, dropout remains ≤0.4V, and load regulation stays within 0.2 mV/mA. Exceeding 15mA may cause output collapse or thermal shutdown.
Does MAX6033CAUT50#TG16 require an input bypass capacitor?
Yes - a minimum 0.1µF ceramic capacitor is recommended between IN and GND, placed as close as possible to the MAX6033CAUT50#TG16 pins. This improves line-transient response and prevents instability during supply fluctuations; omission may cause overshoot or oscillation under fast input steps.
How does the force-sense (OUTF/OUTS) configuration improve accuracy in MAX6033CAUT50#TG16?
The OUTF/OUTS pair in MAX6033CAUT50#TG16 enables Kelvin sensing: OUTF delivers current to the load, while OUTS samples voltage directly at the load node. This compensates for voltage drop across PCB traces and connectors, ensuring the regulated 5.000V is maintained precisely at the point-of-load - critical for remote ADC references.
Is MAX6033CAUT50#TG16 qualified for automotive applications?
Yes - MAX6033CAUT50#TG16 is specified and tested over −40°C to +125°C, with guaranteed parameters including 40ppm/°C tempco, ±0.10% initial accuracy, and 150ppm temperature hysteresis. Its SOT23 package and BiCMOS process meet AEC-Q100 stress test requirements for automotive under-hood use.
What is the minimum output capacitance required for stability with MAX6033CAUT50#TG16?
MAX6033CAUT50#TG16 requires a minimum 0.1µF ceramic output capacitor between OUTS and GND for guaranteed stability. It remains stable with capacitive loads up to 100µF, allowing flexibility in filtering and transient suppression without external compensation components.
