Product details
Overview
MAX6023EBT21-T from Maxim Integrated is a precision, low-dropout, micropower series-mode voltage reference delivering 2.048V output with ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 100mV dropout at 500µA load. It operates from 2.5V to 12.6V input and draws only 27µA typical supply current, making it ideal for high-accuracy, battery-powered data acquisition systems.
For engineers reviewing the MAX6023EBT21-T datasheet, MAX6023EBT21-T pinout, MAX6023EBT21-T application, or MAX6023EBT21-T equivalent, key selection criteria include guaranteed -40°C to +85°C operation, UCSP-5 package footprint (1.0mm × 1.5mm × 0.3mm), no external capacitor requirement, and stable performance up to 2.2nF capacitive load.
Technical Context
The MAX6023EBT21-T uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift and ±0.2% initial accuracy across -40°C to +85°C. Its series-mode architecture enables sourcing/sinking up to 500µA while maintaining low dropout (100mV @ 500µA) and minimal supply current variation (0.8µA/V).
This device is internally compensated and requires no external output capacitor for stability-verified over 0–2.2nF load capacitance. Its line regulation (≤100µV/V) and load regulation (≤1.4µV/µA) ensure stable reference performance under varying supply and load conditions in precision analog signal chains.
Key Specifications

FAQ
What is the maximum load current supported by MAX6023EBT21-T while maintaining regulation?
MAX6023EBT21-T supports up to ±500µA load current (sourcing or sinking) while maintaining output regulation within specifications. At 500µA sink current, dropout voltage remains ≤200mV; the device remains stable and accurate across this full range, enabling direct driving of ADC reference inputs, op-amp bias networks, and comparator thresholds without external buffering.
Does MAX6023EBT21-T require an external output capacitor for stability?
No, MAX6023EBT21-T does not require an external output capacitor for stability. It is internally compensated and guaranteed stable with capacitive loads from 0 to 2.2nF. This eliminates BOM cost and PCB area typically needed for decoupling caps, while also removing potential failure modes associated with ceramic capacitor aging or microphonics in vibration-prone environments.
What is the supply voltage range for MAX6023EBT21-T, and how does it differ from other MAX6023 variants?
MAX6023EBT21-T operates from 2.5V to 12.6V input - identical to the 1.25V variant (MAX6023EBT12-T) but distinct from higher-output versions (e.g., 2.5V+), which require VIN ≥ VOUT + 0.2V. This wider input range simplifies power supply design in multi-rail systems and enables compatibility with legacy 3.3V or 5V supplies without additional regulators.
How does the UCSP package of MAX6023EBT21-T impact PCB assembly and reliability?
The UCSP package of MAX6023EBT21-T requires adherence to JEDEC J-STD-020A reflow profiles (IR/VPR/convection only; no hand or wave soldering). Its reliability depends on user-controlled factors: PCB material (FR-4 recommended), solder paste volume, and thermal profile. Maxim provides UCSP reliability guidelines, and the package delivers proven performance in high-volume consumer and industrial applications when assembly best practices are followed.
What is the turn-on settling time specification for MAX6023EBT21-T?
MAX6023EBT21-T achieves output settling within 0.1% of final value in ≤85µs (typical) with a 50pF load capacitor. This fast turn-on time supports power-gating strategies in battery-powered systems - allowing the reference to be enabled only during ADC conversion cycles, thereby minimizing average current draw without sacrificing measurement accuracy or timing predictability.
