Overview
The MAX6037BAUKADJ+T is a low-power, adjustable series voltage reference in a 5-pin SOT-23 package. It provides an output range of 1.184V to 5V via an external resistive divider. The device operates from a 2.5V to 5.5V supply with a maximum quiescent current of 275µA and features active-low shutdown drawing less than 500nA. It offers ±0.3% initial accuracy and a 50ppm/°C temperature coefficient. The output can source and sink up to 5mA with a maximum dropout voltage of 410mV at 5mA load.
Feature Summary
- Adjustable output voltage set by external resistor divider
- Active-low shutdown mode for ultra-low power consumption
- Low dropout voltage capability for battery-powered systems
- High precision with specified initial accuracy and temperature stability
Applications
- Portable equipment
- Medical equipment
- Wireless LAN systems
- Precision regulators
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'B' grade designation matches the required ±0.3% accuracy and 50ppm/°C temperature coefficient specifications. Ensure the lead-free '+T' marking aligns with environmental compliance requirements for the target assembly process.
Selection Notes
Select this part when an adjustable reference voltage between 1.184V and 5V is required in a compact SOT-23 footprint. It is suitable for applications needing shutdown functionality to extend battery life. Compare against fixed-output variants if a standard voltage like 3.3V or 2.5V suffices, as they may offer different cost or availability profiles.
Part Context
This component belongs to the MAX6037 family of micropower voltage references manufactured by Analog Devices (Maxim Integrated). The family includes both fixed and adjustable versions designed for low-voltage, battery-operated applications. The BAUKADJ variant specifically denotes the B-grade accuracy and adjustable output configuration within the SOT-23-5 package line.
Replacement Considerations
Direct substitutes include other MAX6037 family members such as MAX6037AAUKADJ+T or MAX6037CAUKADJ+T, which share the same package and pinout but differ in accuracy grades. Fixed-output equivalents like MAX6037BAUK33+T are functionally similar but lack adjustability.
