MAX6150ESA

Overview

The MAX6150ESA is a low-dropout, micropower three-terminal voltage reference providing a fixed 5.0V output. It operates with a supply voltage range of 5.2V to 12.6V and draws a quiescent current of approximately 80µA at +25°C. The device features an initial accuracy of ±1% and a typical temperature coefficient of 15ppm/°C. Designed for 3V and 5V systems, it offers a low dropout voltage of 200mV and remains stable for capacitive loads up to 10nF without requiring an output capacitor.

Feature Summary

• Low dropout voltage of 200mV optimized for 3V and 5V system operation
• Micropower consumption with supply current virtually independent of input voltage variations
• Stable for all capacitive loads up to 10nF without external output capacitance

Applications

• Battery-powered systems
• Portable and hand-held equipment
• Data-acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the specific package type and temperature rating against the datasheet before procurement. Confirm that the input voltage supplied to the device falls within the specified operational range to ensure proper regulation. Check for any RoHS compliance markings if required by your manufacturing standards. Ensure the load does not exceed the continuous power dissipation limits under worst-case thermal conditions.

Selection Notes

Select this component when a fixed 5.0V precision reference is needed in space-constrained designs. It is suitable for applications where battery life is critical due to its low, input-voltage-independent supply current. Consider the 8-pin SO package for PCB layout requirements. Verify that the maximum output current demand stays within the safe operating area defined in the electrical characteristics.

Part Context

This part belongs to the MAX61xx family of low-cost, low-dropout, micropower voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with different fixed output voltages (2.5V, 4.096V, 4.5V) and an adjustable version. These devices share common architectural features such as low dropout voltage and micropower operation, designed primarily for portable and battery-operated electronics.

Replacement Considerations

Direct substitutes within the same family include MAX6125ESA (2.5V), MAX6141ESA (4.096V), and MAX6145ESA (4.5V). For adjustable output needs, the MAX6160ESA can be configured using external resistors. Ensure the replacement maintains the required output voltage and package compatibility.
