Analog Devices Inc./Maxim Integrated MAX6023EBT30+T

Overview

MAX6023EBT30+T from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference in a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), delivering a stable 3.000V output with ±0.20% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA load - optimized for battery-operated data acquisition and industrial control systems.

For engineers reviewing the MAX6023EBT30+T datasheet, MAX6023EBT30+T pinout, MAX6023EBT30+T application, or MAX6023EBT30+T equivalent, key selection criteria include its ultra-low quiescent current (35µA max), input voltage range of (VOUT + 0.2V) to 12.6V, no-output-capacitor stability up to 2.2nF, and UCSP footprint constraints for height- and space-sensitive PCB layouts.

Technical Context

The MAX6023EBT30+T uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift and ±0.20% initial accuracy across –40°C to +85°C. It operates as a three-terminal series-mode reference, sourcing/sinking up to ±500µA while maintaining regulation under 200mV dropout.

Its supply current varies only 0.8µA/V with input voltage changes, enabling predictable power budgeting in wide-input-voltage systems. Internally compensated, it requires no external capacitor and remains stable with capacitive loads from 0 to 2.2nF - eliminating layout-dependent instability risks common in shunt-mode alternatives.

FAQ

What is the minimum input voltage required for stable operation of MAX6023EBT30+T?

The MAX6023EBT30+T requires a minimum input voltage of (VOUT + 0.2V) = 3.2V for guaranteed regulation across temperature and load. Below this, output accuracy degrades and dropout behavior becomes undefined. The device supports inputs up to 12.6V, and its line regulation is specified over this full range - ensuring consistent performance in variable-supply environments like battery-backed systems.

Does MAX6023EBT30+T require an external output capacitor?

No, MAX6023EBT30+T does not require an external output capacitor for stability - it is internally compensated and remains oscillation-free with capacitive loads from 0 to 2.2nF. An optional capacitor may be added to improve transient response during large load steps, but it is never mandatory. This eliminates capacitor-related failure modes and saves PCB area in miniaturized designs.

What is the maximum load current that MAX6023EBT30+T can source or sink?

MAX6023EBT30+T can source or sink up to ±500µA while maintaining output regulation within specifications. At 500µA load, dropout voltage is guaranteed ≤200mV, and load regulation is ≤1.5µV/µA - meaning total output deviation stays within ±750µV. Exceeding ±500µA may cause output droop or instability, especially near minimum input voltage.

How does the supply current of MAX6023EBT30+T vary with input voltage?

MAX6023EBT30+T exhibits exceptionally stable supply current: it varies by only 0.8µA per volt of input voltage change over its operating range. For example, supply current increases by just 2.4µA when VIN rises from 3.2V to 6.2V. This near-constant current draw simplifies power budgeting and extends battery life predictably - unlike shunt references whose current scales with worst-case load.

Is MAX6023EBT30+T compatible with standard reflow soldering processes?

Yes, MAX6023EBT30+T is qualified for JEDEC J-STD-020D-compliant reflow profiles, including peak temperatures up to +260°C. However, due to its UCSP construction, preheating is mandatory and hand/wave soldering is prohibited. Board design must follow Maxim's UCSP layout guidelines - particularly regarding solder mask openings, pad geometry, and thermal relief - to ensure reliable bump attachment and long-term mechanical integrity.
