Product details
Overview
The MAX6033BAUT50#TG16 from Maxim Integrated is a precision series voltage reference IC delivering a stable 5.000V output with ±0.20% initial accuracy, 15ppm/°C max temperature coefficient over –40°C to +125°C, and ultra-low 40µA quiescent current. It features low dropout (200mV max at 1mA), excellent load regulation (0.003 mV/mA typ), and is optimized for high-resolution data converters in automotive and industrial systems.
For engineers reviewing the MAX6033BAUT50#TG16 datasheet, MAX6033BAUT50#TG16 pinout, MAX6033BAUT50#TG16 application, or MAX6033BAUT50#TG16 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX6033BAUT50#TG16 is a bandgap-based series voltage reference using laser-trimmed thin-film resistors and post-package trimming to achieve ±0.20% initial accuracy and 15ppm/°C max tempco over –40°C to +125°C. Its dual-output architecture (OUTF/OUTS) enables remote sensing for improved load regulation under varying PCB trace impedances.
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. The device exhibits 40µVP-P (0.1Hz–10Hz) output noise and settles within 1000µs to ±0.01% of final value during turn-on.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.20% at +25°C - ensures DAC/ADC reference accuracy without calibration in mid-precision systems |
| Temp Coefficient | 15ppm/°C max (–40°C to +125°C) - limits drift to ±750µV over full automotive range |
| Dropout Voltage | 200mV max at 1mA - enables operation from 5.2V supply with margin for ripple and drop |
| Quiescent Current | 40µA typ - reduces system power by >90% vs. shunt references in battery-powered instruments |
| Load Regulation | 0.003 mV/mA typ - holds output within ±15µV across 0–15mA load variation |
| Noise (0.1–10Hz) | 40µVP-P - avoids LSB errors in 16-bit+ ADCs with ≥5VFS range |
| Input Voltage Range | 5.2V to 12.6V - supports direct connection to unregulated 6V–12V rails common in automotive ECUs |
Pinout & Package
MAX6033BAUT50#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline, land pattern 90-0175), rated for –40°C to +125°C operation and suitable for high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | Not externally accessible; internal connection only - must remain unconnected on PCB |
| 2 | GND | Analog ground reference - requires low-impedance connection to system AGND plane |
| 4 | IN | Positive supply input - accepts 5.2V–12.6V; bypass with 0.1µF ceramic capacitor near pin |
| 5 | OUTF | Force output - drives load; connect directly to OUTS near device for Kelvin sensing |
| 6 | OUTS | Sense input - monitors feedback point at load; enables <0.01% load regulation error |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDR | 5.0V output, 3ppm/°C max tempco, 0.05% initial accuracy, 950µA IQ, SOIC-8 | Higher accuracy and lower drift, but 24× higher supply current and larger package | Choose REF5050IDR when absolute drift <10ppm/°C is required and board space/power budget allow SOIC-8 |
| ADR4550BRZ | 5.0V output, 3ppm/°C max tempco, 0.02% initial accuracy, 950µA IQ, SOIC-8 | Superior long-term stability (15ppm/1000hr) and lower noise (12µVP-P), but incompatible SOT23 footprint | Choose ADR4550BRZ for metrology-grade systems where performance outweighs size/power constraints |

FAQ
What is the guaranteed initial accuracy of MAX6033BAUT50#TG16 over temperature?
The MAX6033BAUT50#TG16 guarantees ±0.20% initial accuracy at +25°C, with no additional tolerance added for temperature - its 15ppm/°C max tempco defines the full-range drift separately. Over –40°C to +125°C, total error remains within ±0.20% plus ±0.0075% (15ppm × 50°C span), resulting in worst-case ±0.2075% output deviation from nominal 5.000V.
Can MAX6033BAUT50#TG16 drive a 10µF ceramic capacitor directly at its output?
Yes, MAX6033BAUT50#TG16 is explicitly characterized stable with capacitive loads up to 100µF, including 10µF ceramics. This allows robust EMI filtering and improved transient response in noisy automotive environments without requiring external compensation or isolation resistors.
What is the minimum input voltage required for MAX6033BAUT50#TG16 to maintain regulation at 15mA load?
At 15mA load and –40°C to +125°C, the MAX6033BAUT50#TG16 requires VIN ≥ 5.5V to maintain regulation - derived from its 500mV max dropout voltage (per Electrical Characteristics table, VDO at IOUT = 10mA, TA = –40°C to +125°C) plus nominal 5.000V output. Thus, 5.000V + 0.5V = 5.5V minimum.
How does the OUTF/OUTS pin configuration improve performance in MAX6033BAUT50#TG16?
The OUTF/OUTS configuration implements true Kelvin sensing: OUTF sources current to the load while OUTS senses voltage at the load point. This cancels voltage drop across PCB traces and connectors, reducing load regulation error from typical 0.1mV/mA to 0.003mV/mA - critical for maintaining ADC accuracy in distributed sensor systems.
Is MAX6033BAUT50#TG16 qualified for automotive applications?
Yes, MAX6033BAUT50#TG16 is specified over –40°C to +125°C, packaged in RoHS-compliant SOT23, and built on Maxim's automotive-qualified BiCMOS process. While not formally AEC-Q200 certified as a discrete component, its electrical specs, thermal rating, and qualification history align with AEC-Q100 Grade 1 requirements for voltage references used in engine control, body electronics, and ADAS subsystems.
