MAX6023EBT21+T

Overview

The MAX6023EBT21+T is a precision series-mode voltage reference from Analog Devices/Maxim Integrated, housed in a 5-bump UCSP-5 package. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.2% and a temperature coefficient of 30ppm/°C over the -40°C to +85°C range. The device operates with input voltages from 2.5V to 12.6V, drawing a maximum quiescent supply current of 35µA. It features low dropout characteristics and stability for capacitive loads up to 2.2nF without requiring external compensation.

Feature Summary

• Precision bandgap architecture utilizing curvature correction and laser-trimmed thin-film resistors
• Ultra-small 5-bump UCSP chip-scale package design for height-critical applications
• Micropower operation with minimal supply current variation relative to input voltage changes
• Inherently stable performance across a wide capacitive load range without external components

Applications

• Hand-held equipment
• Data acquisition systems
• Industrial and process control systems
• Battery-operated equipment
• Hard-disk drives

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm that the component is RoHS compliant as per manufacturer specifications. Ensure assembly methods adhere to JEDEC standards for UCSP reliability, as mechanical stress sensitivity differs from traditional packages. Cross-reference the exact part number with authorized distributors to confirm availability status.

Selection Notes

Select this component when a fixed 2.048V reference is required in space-constrained designs. The UCSP package offers a significantly smaller footprint compared to SC70 or SOT23 options. Consider the 35µA supply current for battery life optimization. Verify that the input voltage range meets the system's minimum dropout requirements for the intended load current.

Part Context

This part belongs to the MAX6023 family of low-dropout, micropower voltage references. Other variants in the series offer different fixed output voltages such as 1.25V, 2.5V, 3.0V, 4.096V, 4.5V, and 5.0V, all sharing the same UCSP-5 package and general electrical characteristics regarding accuracy and temperature drift.

Replacement Considerations

Direct substitutes within the same family include MAX6023EBT12+T (1.25V), MAX6023EBT25+T (2.5V), MAX6023EBT30+T (3.0V), MAX6023EBT41+T (4.096V), MAX6023EBT45+T (4.5V), and MAX6023EBT50+T (5.0V). These share identical package dimensions and pinouts but differ in output voltage.
