Product details
Overview
MAX6150EUR+T from Maxim Integrated is a 5.0V, low-dropout, micropower, three-terminal voltage reference in a 3-pin SOT23-3 package, featuring 200mV dropout, ±1% initial accuracy, and 15ppm/°C typical temperature coefficient. It delivers stable 5.0V output for precision analog signal chains in battery-powered instrumentation and portable data-acquisition systems.
For engineers reviewing the MAX6150EUR+T datasheet, MAX6150EUR+T pinout, MAX150EUR+T application, or MAX6150EUR+T equivalent, key selection criteria include dropout voltage at 1mA load, supply current stability over input voltage range, thermal hysteresis (80ppm), load regulation (0.65–2 mV/mA), and compatibility with capacitive loads up to 10nF without oscillation.
Technical Context
The MAX6150EUR+T employs a bandgap-based reference core with internal trimming for ±1% initial accuracy and operates across -40°C to +85°C. Its 200mV dropout enables use with 3V and 5V supplies, while supply current remains stable (75–110µA) over VIN = 5.2V to 12.6V.
It features guaranteed 50ppm/°C max temperature coefficient, 35µVP-P (0.1Hz–10Hz) output noise, and load regulation of ≤2 mV/mA when sourcing 0–1mA - critical for high-resolution ADC/DAC biasing and sensor excitation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±1% at +25°C; 4.900V to 5.100V over full temperature range - ensures stable reference for 12-bit+ converters. |
| Dropout Voltage | 200mV at 1mA load - supports operation from 5.2V input in 5V systems with margin. |
| Supply Current | 80µA typ / 145µA max over temperature - enables multi-year battery life in low-power IoT sensors. |
| Tempco | 15ppm/°C typ / 50ppm/°C max - limits drift to ±250µV over 0–70°C ambient. |
| Load Regulation | 0.65–2.0 mV/mA sourcing/sinking - maintains accuracy under dynamic DAC or op-amp load changes. |
| Line Regulation | 1µV/V typ - rejects input ripple and supply variation in noisy embedded power rails. |
| Output Noise | 35µVP-P (0.1Hz–10Hz), 900µVRMS (10Hz–10kHz) - suitable for 16-bit SAR ADC reference inputs. |
Pinout & Package
MAX6150EUR+T is housed in a RoHS-compliant 3-pin SOT23-3 package (JEDEC MO-178AB), with 1.3mm × 0.8mm footprint and 1.0mm height. Pin 1 = IN, Pin 2 = OUT, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.2V to 12.6V; must be ≥ VOUT + 200mV for regulation; bypass with 0.1µF ceramic near pin. |
| 2 (OUT) | Stable 5.0V reference output | Drives capacitive loads up to 10nF; no external capacitor required; connects directly to ADC REF+, DAC VREF, or op-amp non-inverting input. |
| 3 (GND) | Analog ground reference | Low-impedance return path; must be star-connected to system AGND to minimize noise coupling into reference node. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout (200mV) | Enables regulation from 5.2V supply in 5V systems, preserving headroom for LDO post-regulation or logic interfacing. |
| Supply current independence | IQ varies only 1.7–6 µA/V over VIN range - eliminates need for input voltage compensation in battery-gauge algorithms. |
| Capacitive load stability | Stable with 0–10nF output capacitance - allows direct connection to sampling capacitors in switched-capacitor ADCs without phase-margin risk. |
| Thermal hysteresis | 80ppm max - ensures repeatable output after thermal cycling, critical for calibration-critical test equipment. |
| PSRR > 60dB @ 1kHz | Rejects switching regulator ripple and digital noise on shared supply rails, maintaining reference integrity in mixed-signal SoCs. |
Applications
| Portable Data Loggers | Industrial Sensor Transmitters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3450ARJZ-R7 | 5.0V output, 10ppm/°C max tempco, 4.5µA quiescent current, SOT23-5 package with enable pin. | Lower power but requires PCB layout change (5-pin vs 3-pin); enable function adds control flexibility but increases BOM count. | Select ADR3450ARJZ-R7 only if ultra-low IQ (<5µA) and shutdown capability are mandatory; otherwise MAX6150EUR+T offers simpler integration and lower cost. |
| REF5050AIDBVR | 5.0V output, 3ppm/°C max tempco, 950µA IQ, SO-8 package; higher precision, higher power, larger footprint. | Targeted at lab-grade instrumentation; unsuitable for space-constrained portable designs due to SO-8 size and 13× higher supply current. | Choose REF5050AIDBVR only for metrology-grade applications demanding sub-10ppm stability; MAX6150EUR+T balances cost, size, and performance for industrial portables. |
Compared with ADR3450ARJZ-R7 and REF5050AIDBVR, the MAX6150EUR+T provides optimal trade-off of 5.0V accuracy, 200mV dropout, and 3-pin SOT23 simplicity for battery-operated systems where moderate precision and minimal board area are prioritized over ultra-low IQ or laboratory-grade stability.

FAQ
What is the minimum input voltage required for the MAX6150EUR+T to maintain regulation?
The MAX6150EUR+T requires a minimum input voltage of 5.2V to maintain 5.0V output regulation, based on its guaranteed 200mV dropout voltage at 1mA load. At temperatures beyond +25°C or higher output currents, VIN should be increased marginally to ensure stable operation across the full -40°C to +85°C range. The absolute maximum input is 12.6V.
Does the MAX6150EUR+T require an output capacitor for stability?
No, the MAX6150EUR+T does not require an output capacitor. It is internally compensated and remains stable with capacitive loads ranging from 0nF to 10nF. Adding capacitance beyond 10nF may degrade transient response or cause instability; therefore, output bypassing is optional and only recommended for charge reservoir purposes in DAC interface applications.
How does supply current vary with input voltage in the MAX6150EUR+T?
The MAX6150EUR+T exhibits exceptional supply current stability: IQ changes by only 1.7–6 µA per volt across VIN = 5.2V to 12.6V. At +25°C, typical IQ is 80µA and remains nearly constant - unlike two-terminal references, this independence eliminates input-voltage-dependent battery drain, extending operational life in coin-cell or Li-ion powered devices.
What is the thermal hysteresis specification for the MAX6150EUR+T, and why does it matter?
The MAX6150EUR+T has a thermal hysteresis of 80ppm, measured after cycling between -40°C and +85°C. This parameter quantifies residual output voltage shift after temperature-induced mechanical stress relaxation in the silicon die and package. In field-deployed instruments subject to repeated thermal cycling, low hysteresis ensures calibration retention and measurement repeatability without periodic recalibration.
Can the MAX6150EUR+T be used in place of the MAX6150ESA?
Yes, the MAX6150EUR+T is the 3-pin SOT23-3 packaged variant of the same 5.0V reference device as the 8-pin SO-packaged MAX6150ESA. Both share identical electrical specifications, temperature range (-40°C to +85°C), and pin functions (IN, OUT, GND). The only differences are package size, thermal resistance, and top-mark code (EEAA vs blank); no circuit redesign is needed when substituting MAX6150EUR+T for MAX6150ESA in new layouts.
