Overview
The MAX6003EUR+T is a micropower, low-dropout series voltage reference from the MAX6001–MAX6005 family. It provides a fixed output voltage of 3.0V with a maximum initial accuracy of 1% and a temperature coefficient of 100ppm/°C. The device operates within an input voltage range of (VOUT + 0.2V) to 12.6V and draws a quiescent supply current of up to 45µA. It features ±400µA output source and sink current capability, stable operation with capacitive loads up to 2.2nF, and is housed in a space-saving SOT-23-3 package.
Feature Summary
- Eliminates the need for external resistors or compensation capacitors through internal design.
- Offers supply current virtually independent of the supply voltage to maximize efficiency.
- Capable of sourcing and sinking up to 400µA with minimal dropout voltage.
Applications
- Portable and battery-powered equipment
- Notebook computers
- PDAs, GPSs, and digital multimeters
- Cellular phones
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm the 3.0V output variant. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference datasheet specifications with procurement requirements to validate performance parameters before integration.
Selection Notes
Select this component for applications requiring low power dissipation and wide supply voltage variations. It is suitable for cost-sensitive designs where board space is limited due to the compact SOT-23-3 package. Consider its low dropout characteristics for efficient operation in low-voltage battery systems.
Part Context
This device belongs to the MAX6001–MAX6005 family of low-cost, low-power voltage references. These devices combine the cost advantages of shunt references with the power-saving benefits of series references. The family is designed for high-volume, battery-operated systems requiring very low power dissipation.
Replacement Considerations
Other members of the MAX6001–MAX6005 family share identical pinouts and packages but offer different fixed output voltages. Verify that the alternative part number corresponds to the required output voltage level for the specific application circuit.
