Product details
Overview
MAX6033AAUT50#TG16 from Maxim Integrated is an ultra-high-precision, low-dropout series voltage reference delivering a stable 5.000V output with ±0.04% initial accuracy, 7ppm/°C max temperature coefficient, and 40µA quiescent current. It operates over -40°C to +125°C and supports up to 15mA load current, making it suitable for high-resolution ADC/DAC biasing in automotive and industrial measurement systems.
For engineers reviewing the MAX6033AAUT50#TG16 datasheet, MAX6033AAUT50#TG16 pinout, MAX6033AAUT50#TG16 application, or MAX6033AAUT50#TG16 equivalent, key selection criteria include guaranteed 5.000V output accuracy at +25°C (±0.04%), automotive-grade tempco performance (≤10ppm/°C over -40°C to +125°C), dropout voltage ≤200mV at 1mA, stability with capacitive loads up to 100µF, and SOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6033AAUT50#TG16 employs bandgap-based architecture with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.04% initial accuracy and 7ppm/°C max tempco over -40°C to +85°C. Its dual-output force-sense topology (OUTF/OUTS) enables precise regulation under varying load conditions while maintaining low noise (40µVP-P, 0.1Hz–10Hz).
Designed as a series-mode reference, it eliminates external pass transistors and reduces system power vs. shunt alternatives. Input voltage range spans 5.2V to 12.6V, supporting operation with minimal headroom-critical for battery-powered instrumentation where dropout voltage ≤200mV at 1mA ensures efficiency near end-of-life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.04% at +25°C - guarantees absolute reference accuracy for 16-bit+ data converters without calibration. |
| Tempco | ≤10ppm/°C over -40°C to +125°C - ensures <±0.5mV drift across full automotive temperature range. |
| Dropout Voltage | ≤200mV at 1mA load - enables operation from 5.2V supply, reducing power loss in low-headroom systems. |
| Quiescent Current | 40µA typical - minimizes standby power in portable/handheld instruments with multi-year battery life. |
| Noise (0.1–10Hz) | 40µVP-P - limits quantization error in 20-bit+ ADCs used in precision weigh scales and sensor front-ends. |

| Capacitive Load Stability | Stable with 0.1µF to 100µF - allows flexible bypassing for EMI suppression or transient response tuning without oscillation risk. |
Pinout & Package
The MAX6033AAUT50#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline), with 1.6mm × 2.9mm footprint and 1.1mm height, optimized for high-density automotive and industrial PCBs.
| 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 ground plane to minimize noise coupling. |
| 4 | IN | Positive input supply (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 OUTS via shortest possible trace to maintain regulation accuracy. |
| 6 | OUTS | Sense node for feedback; monitors actual output voltage at load point to compensate for trace resistance and IR drop. |

FAQ
What is the guaranteed initial accuracy of the MAX6033AAUT50#TG16 at +25°C?
The MAX6033AAUT50#TG16 is guaranteed to deliver ±0.04% initial output voltage accuracy at +25°C, corresponding to a 5.000V nominal output spanning 4.9980V to 5.0020V. This specification is laser-trimmed and verified during 100% production testing, ensuring consistent performance without post-manufacture calibration for high-volume sensor modules and data acquisition systems.
Does the MAX6033AAUT50#TG16 support operation across the full automotive temperature range?
Yes, the MAX6033AAUT50#TG16 is fully specified and guaranteed over -40°C to +125°C. Its temperature coefficient is ≤10ppm/°C across this range, and all electrical parameters-including dropout voltage, load regulation, and quiescent current-are validated per the datasheet's operating conditions. This makes MAX6033AAUT50#TG16 suitable for under-hood automotive applications and industrial controls exposed to extreme ambient temperatures.
How does the OUTF/OUTS pin configuration improve reference accuracy in the MAX6033AAUT50#TG16?
The MAX6033AAUT50#TG16 uses separate force (OUTF) and sense (OUTS) outputs to compensate for voltage drop across PCB traces and interconnects. By routing OUTS directly to the load point and shorting it to OUTF near the device, the internal regulator adjusts OUTF to maintain exact voltage at the sense node-effectively eliminating errors from trace resistance up to ~1Ω. This topology is critical for remote ADC/DAC referencing in distributed sensor systems.
What is the maximum capacitive load the MAX6033AAUT50#TG16 can drive while remaining stable?
The MAX6033AAUT50#TG16 is stable with output capacitance ranging from 0.1µF minimum to 100µF maximum, including ceramic, tantalum, and electrolytic types. This wide range allows designers to select capacitors based on EMI filtering, transient response, or physical size constraints without risking oscillation-unlike many references requiring narrow COUT windows. The 0.1µF minimum also simplifies layout in space-limited applications.
What is the dropout voltage specification for the MAX6033AAUT50#TG16 at 10mA load current?
At 10mA load current and -40°C to +125°C, the MAX6033AAUT50#TG16 has a maximum dropout voltage of 0.5V. At room temperature (+25°C), the typical dropout is 0.2V–0.4V depending on current. This low dropout enables operation from supplies as low as 5.2V (5.0V + 0.2V), making MAX6033AAUT50#TG16 ideal for battery-powered systems where supply voltage sags near end-of-life.
