MAX6195CESA

Overview

The MAX6195CESA+ is a precision, micropower, low-dropout voltage reference featuring a fixed 5.000V output. It utilizes a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve high initial accuracy of ±25mV and a maximum temperature coefficient of 25ppm/°C. The device draws a maximum quiescent supply current of 35µA and supports source/sink currents up to 500µA with a dropout voltage of approximately 200mV at full load. It operates within an input voltage range of VOUT + 0.2V to 12.6V and is housed in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high initial accuracy and very low temperature drift.
• Micropower series-mode architecture provides a maximum quiescent supply current of 35µA that remains virtually independent of input voltage variations.
• Capable of sourcing and sinking up to 500µA while maintaining stability with capacitive loads ranging from 0 to 2.2nF without external compensation.

Applications

• Hand-Held Instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'CESA+' corresponds to the required accuracy grade (±25mV) and temperature range (-40°C to +85°C). Confirm the package type matches the design footprint. Ensure the input voltage source can provide transient currents exceeding nominal levels during turn-on to guarantee reliable startup behavior.

Selection Notes

Select this component when a fixed 5V reference is required for battery-powered applications due to its low quiescent current. It is suitable for designs needing fast settling times and internal compensation. Consider alternative grades if tighter accuracy or lower temperature coefficients are necessary for the specific application requirements.
