LTC6655BHMS8-3.3#TRPBF

Overview

The LTC6655BHMS8-3.3#TRPBF is a precision bandgap voltage reference providing a fixed 3.3V output with ±0.025% initial accuracy and a maximum temperature coefficient of 2ppm/°C. It operates within a supply range of VOUT + 0.5V to 13.2V, drawing 7mA typical supply current. The device features low noise performance of 0.25ppm peak-to-peak (0.1Hz to 10Hz) and supports ±5mA source/sink currents. Packaged in an 8-lead MSOP, it includes a shutdown mode consuming less than 20µA and is fully specified over the –40°C to 125°C temperature range.

Feature Summary

• Advanced curvature compensation ensures predictable temperature characteristics and high accuracy without calibration.
• Superior load regulation and line rejection maintain consistent performance across wide operating conditions.
• Integrated shutdown mode significantly reduces power consumption for low-power applications.

Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• Precision battery monitors

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the B grade designation corresponds to the required ±0.025% accuracy and 2ppm/°C drift specifications. Ensure the MSOP package variant matches the target PCB footprint requirements.

Selection Notes

Select this component for designs requiring minimal calibration due to its high initial accuracy and low drift. Consider the 7mA supply current against system power budgets. Verify that the 500mV dropout voltage aligns with the available input supply headroom for the 3.3V output.
