Product details
Overview
MAX6150EUR-T from Maxim Integrated is a precision 5.0V, low-dropout, micropower, three-terminal voltage reference in a 3-pin SOT23-3 package. It delivers ±1% initial accuracy, 15ppm/°C typical temperature coefficient (≤50ppm/°C max), and 200mV dropout at 1mA load-enabling stable operation in 3V/5V battery-powered systems such as portable data-acquisition front-ends.
For engineers reviewing the MAX6150EUR-T datasheet, MAX6150EUR-T pinout, MAX6150EUR-T application, or MAX6150EUR-T equivalent, key selection criteria include its 80µA typical supply current (independent of input voltage), 35µVP-P output noise (0.1Hz–10Hz), and guaranteed stability with capacitive loads up to 10nF without requiring an output capacitor.
Technical Context
The MAX6150EUR-T implements a bandgap-based reference core with internal trimming for high initial accuracy and low thermal drift. Its 3-terminal architecture integrates error amplifier, pass element, and feedback network into a single monolithic IC, eliminating external resistors required by two-terminal references.
It operates over VIN = 5.2V to 12.6V and maintains regulation down to 200mV headroom, supporting direct use after LDOs or in 5V rail-sensing applications. Load regulation is specified at 0.65–2.0 mV/mA (sourcing) and 1.9–20 mV/mA (sinking), confirming robustness across 0–1mA output current range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±1% at +25°C; 4.900V to 5.100V over -40°C to +85°C - ensures ADC/DAC biasing within 2% full-scale error across industrial temp range |
| Tempco | 15ppm/°C typical, ≤50ppm/°C max - contributes ≤250µV drift over 50°C ambient swing, critical for 16-bit+ measurement systems |
| Dropout Voltage | 200mV at 1mA load - enables operation from 5.2V input in 5V systems with minimal headroom penalty |
| Supply Current | 80µA typical, ≤145µA over temperature - supports >1-year battery life in 10µA-average-power IoT sensors |
| Output Noise | 35µVP-P (0.1Hz–10Hz), 900µVRMS (10Hz–10kHz) - limits quantization uncertainty in high-resolution SAR ADC references |
| Line Regulation | 1µV/V typical - suppresses input ripple-induced output variation below 5µV per 5V input change |
| Load Regulation | 0.65mV/mA sourcing, 1.9mV/mA sinking - maintains <1mV shift under 1mA dynamic load transients |
Pinout & Package

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 at full load, due to its 200mV dropout specification. At 1mA load, VIN must be ≥5.2V; at lighter loads, regulation holds down to VIN = VOUT + dropout (e.g., 5.05V at 0.25mA). Input below 5.2V risks output collapse or increased tempco error.
Does the MAX6150EUR-T require an output capacitor for stability?
No, the MAX6150EUR-T is internally compensated and stable with capacitive loads from 0nF to 10nF. An output capacitor is not required and may degrade transient response. If used for charge reservoir purposes (e.g., decoupling a DAC input), total output capacitance must remain ≤10nF to preserve settling time performance.
How does supply current vary with input voltage for the MAX6150EUR-T?
The MAX6150EUR-T exhibits near-constant supply current across its input range: 80µA typical at +25°C, varying only ±6µA/V over VIN = 5.2V to 12.6V. This independence from input voltage ensures predictable battery drain in systems with fluctuating supply rails, unlike resistor-biased references.
What is the maximum capacitive load the MAX6150EUR-T can drive while maintaining stability?
The MAX6150EUR-T is guaranteed stable with output capacitive loads from 0nF up to 10nF. Exceeding 10nF may induce oscillation or slow settling. For applications requiring larger bulk capacitance, place it downstream of a series resistor (≥10Ω) to isolate the reference output from the added capacitance.
Can the MAX6150EUR-T be used in a 3.3V system?
No-the MAX6150EUR-T requires a minimum input voltage of 5.2V and is designed for 5V-input systems. For 3.3V systems, consider the MAX6125EUR-T (2.5V output, 2.7V min input) or MAX6141EUR-T (4.096V output, 4.3V min input), both in the same SOT23-3 package and sharing identical micropower and low-dropout characteristics.
