Product details
Overview
MAX6067BEUR+T from Maxim Integrated is a precision, low-dropout, micropower 4.5V voltage reference in a 3-pin SOT23 package. It delivers ±0.2% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA source / 2mA sink load current. Designed for high-accuracy ADC biasing and portable battery-powered systems requiring stable 4.5V reference under varying input and temperature conditions.
For engineers reviewing the MAX6067BEUR+T datasheet, MAX6067BEUR+T pinout, MAX6067BEUR+T application, or MAX6067BEUR+T equivalent, key selection criteria include dropout voltage (≤200mV at 1mA), supply-current independence (90µA typ, ≤8µA/V variation), absence of required output capacitor, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX6067BEUR+T is a three-terminal series-mode voltage reference featuring proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its internal compensation eliminates need for external capacitors, and its supply current remains stable across 4.7V to 12.6V input range (VOUT + 0.2V min).
It operates as a fixed-output, high-output-current reference with 200mV max dropout at 1mA load, 70dB PSRR at 120Hz, and 55µVp-p (0.1Hz–10Hz) output noise - enabling use in precision data acquisition and low-power embedded analog subsystems without stability compromises.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.500V ±0.2% (max initial error) - ensures accurate scaling for 4.5V-referenced 12-/16-bit ADCs and DACs |
| Tempco | 20ppm/°C (max) - limits full-range drift to ≤1.5mV over –40°C to +85°C, critical for field-deployed instrumentation |
| Dropout Voltage | 200mV (max at 1mA load) - enables operation from 4.7V supply, supporting single-cell Li-ion or regulated 5V rails |
| Supply Current | 90µA (typ), ≤8µA/V variation - ultra-low, voltage-independent quiescent draw extends battery life in portable devices |
| Noise (0.1–10Hz) | 55µVp-p - low flicker noise preserves SNR in high-resolution measurement front-ends |
| Load Drive | ±2mA sink / +5mA source - sufficient to drive ADC reference inputs, op-amp bias networks, and small DAC loads directly |
| PSRR | 70dB at 120Hz - rejects ripple from switching regulators or noisy DC/DC outputs feeding the reference input |
Pinout & Package
MAX6067BEUR+T uses a 3-pin SOT23-3 package (JEDEC MO-178AA), 1.3mm × 2.9mm footprint, 1.0mm height, with gull-wing leads. Pin 1 = IN (input voltage), Pin 2 = OUT (4.5V reference output), Pin 3 = GND (ground). The device is top-marked "FZFT" per Maxim's ordering guide.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply terminal | Accepts 4.7V–12.6V; requires no series resistor; bypassing with 0.1µF ceramic improves line-transient response |
| 2 (OUT) | Precision 4.5V reference output | Stable, low-impedance source/sink node; no external capacitor needed for stability; drives capacitive loads directly |
| 3 (GND) | Analog ground reference | Must be connected to clean system ground plane; shared return path for IN and OUT currents |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 90µA typical, independent of input voltage - reduces standby power in always-on sensor nodes |
| No output capacitor required | Fully internally compensated - saves PCB area and BOM cost in space-constrained wearables and IoT modules |
| Low dropout | 200mV max at 1mA - enables direct regulation from 4.7V sources (e.g., buck-boost converters tracking Li-ion voltage) |
| High output current capability | +5mA source / –2mA sink - eliminates need for external buffer op-amps in most precision analog signal chains |
| Stable with capacitive loads | Operates reliably with ≥0.1µF output capacitance - simplifies EMI filtering and transient suppression design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3045AIDBZR | 4.5V, ±0.2% initial accuracy, 50ppm/°C max tempco, 100µA supply current, SOT23-3 | Higher tempco increases full-range drift by ~2×; higher noise (75µVp-p) | Select when lower cost is prioritized over tempco/noise; verify system-level drift budget allows 50ppm/°C |
| ADR3445ARJZ-R7 | 4.5V, ±0.1% initial accuracy, 10ppm/°C max tempco, 120µA supply current, SOT23-3 | Lower tempco and tighter initial tolerance, but 33% higher supply current and larger dropout (300mV) | Select when ultimate accuracy and stability outweigh battery-life impact; confirm 300mV dropout fits supply headroom |

FAQ
What is the maximum input voltage rating for MAX6067BEUR+T?
The absolute maximum input voltage for MAX6067BEUR+T is +13.5V referenced to GND. However, the recommended operating input range is (VOUT + 0.2V) to +12.6V - i.e., 4.7V to 12.6V - as specified in the Electrical Characteristics table. Exceeding 12.6V may degrade long-term reliability even if within absolute maximum ratings.
Does MAX6067BEUR+T require an external output capacitor for stability?
No, MAX6067BEUR+T does not require an external output capacitor for stability due to internal compensation. It remains stable with capacitive loads up to at least 1µF. An optional 0.1µF ceramic capacitor can be added to improve transient response in high-dynamic-load applications, but it is never mandatory.
What is the guaranteed initial accuracy of MAX6067BEUR+T at +25°C?
The MAX6067BEUR+T is guaranteed to have ±0.2% initial output voltage accuracy at +25°C, corresponding to a 4.5V output tolerance of ±9mV (4.491V to 4.509V). This is the 'B' grade variant per Maxim's ordering guide, distinct from the tighter ±0.1% 'A' grade (MAX6067AEUR+T).
How does the supply current of MAX6067BEUR+T vary with input voltage?
MAX6067BEUR+T exhibits ≤8µA/V variation in supply current across its 4.7V–12.6V input range. At +25°C, typical supply current is 90µA, rising to no more than 125µA over temperature and input extremes - confirming near-voltage-independence critical for battery-operated systems.
Can MAX6067BEUR+T sink current, and what is the maximum sink capability?
Yes, MAX6067BEUR+T can actively sink up to 2mA of load current - essential for driving reference inputs that draw bias current or for active pull-down configurations. This capability is fully characterized from –2mA to 0mA in the Load Regulation specification, with ≤4mV/mA error slope.
