Analog Devices Inc./Maxim Integrated MAX6002EUR/V+T

Overview

MAX6002EUR/V+T from Analog Devices is a precision 2.5V series voltage reference in SOT23-3 package, designed for low-power, wide-input-voltage battery-operated systems. It delivers ±400µA output current capability, 100ppm/°C max temperature coefficient, and 100mV dropout at 400µA load - enabling stable regulation in space-constrained portable electronics such as GPS receivers and handheld DMMs.

For engineers reviewing the MAX6002EUR/V+T datasheet, MAX6002EUR/V+T pinout, MAX6002EUR/V+T application, or MAX6002EUR/V+T equivalent, key selection criteria include initial accuracy (±1%), quiescent supply current (≤45µA), load regulation (0.12µV/µA), and capacitive-load stability up to 2.2nF without external compensation.

Technical Context

The MAX6002EUR/V+T implements a bandgap-based series voltage reference architecture with internal compensation, eliminating need for external capacitors across its full 0–2.2nF load capacitance range. Its supply current remains stable (≤45µA) over input voltages from (VOUT + 200mV) to 12.6V, varying only 0.8µA/V - a critical advantage over shunt references in variable-supply applications.

It supports bidirectional output current (±400µA), enabling both sourcing and sinking for driving ADC references, sensor biasing, or DAC calibration circuits. Dropout voltage is specified at 100mV (max) under 400µA load, ensuring reliable operation down to VIN = 2.7V while maintaining 2.500V ±1% output accuracy over –40°C to +85°C.

FAQ

What is the guaranteed output voltage tolerance for MAX6002EUR/V+T over temperature?

The MAX6002EUR/V+T guarantees 2.500V ±1% (2.475V to 2.525V) over the full –40°C to +85°C operating range, with initial accuracy tested at +25°C and temperature coefficient limited to 100ppm/°C max. This ensures predictable performance in battery-powered devices experiencing ambient thermal variation.

Can MAX6002EUR/V+T operate with zero output capacitance?

Yes, the MAX6002EUR/V+T is stable with C_OUT = 0 to 2.2nF per datasheet specifications - no external capacitor is required. This eliminates board area and BOM cost in space-critical applications like wearable sensors, though adding up to 2.2nF improves transient response to load steps.

What is the minimum input voltage required for regulation at full 400µA load?

The MAX6002EUR/V+T requires a minimum input voltage of V_OUT + 100mV = 2.600V to maintain regulation at 400µA load, per its 100mV dropout specification. At lighter loads, dropout decreases - e.g., ~50mV at 100µA - enabling operation down to ~2.55V in low-current sleep modes.

Does MAX6002EUR/V+T support sinking current, and how much?

Yes, the MAX6002EUR/V+T supports bidirectional output current: it can source 0 to +400µA and sink 0 to –400µA. This enables active pull-down for reference buffering, sensor excitation reversal, or interfacing with op-amps requiring sink capability - all while maintaining 2.500V accuracy within spec.

How does the supply current of MAX6002EUR/V+T vary with input voltage?

The MAX6002EUR/V+T exhibits only 0.8µA/V variation in supply current across its input range (2.7V to 12.6V), with total quiescent current capped at 45µA. This near-constant draw - unlike shunt references - maximizes battery efficiency in systems with fluctuating supply rails, such as boost-regulated battery packs.
