LT1790BCS6-2.048#TRPBF

Voltage Reference Overview

The LT1790BCS6-2.048#TRPBF is a micropower low dropout series voltage reference manufactured by Analog Devices Inc., housed in a 6-lead plastic TSOT-23 package. It provides a fixed output voltage of 2.048V with an initial accuracy of ±0.1% (B Grade). The device features a maximum temperature coefficient of 25ppm/°C and operates within a supply voltage range of 2.8V to 18V. It draws a maximum no-load supply current of 80µA and supports both sourcing up to 5mA and sinking up to 3mA currents.

Voltage Reference Feature Summary

• Curvature compensation and post-package trimming ensure high output accuracy and low drift.
• Capable of operating as a positive or negative voltage reference by sourcing or sinking current.
• Designed for battery-operated systems with low power dissipation and small package size.

Voltage Reference Applications

• Handheld Instruments
• Negative Voltage References
• Industrial Control Systems
• Data Acquisition Systems
• Battery-Operated Equipment

Voltage Reference Procurement Notes

Verify the specific B grade accuracy and 25ppm/°C temperature coefficient requirements against the datasheet specifications. Confirm that the 6-lead TSOT-23 package footprint matches the design layout. Ensure the supply voltage remains above the minimum dropout threshold for the intended load conditions.

Voltage Reference Selection Notes

Select this component when a compact, low-power reference with moderate precision is required. The B grade offers a balance between cost and performance compared to the higher precision A grade. Consider the thermal hysteresis characteristics if the device will undergo significant temperature cycling during operation.

Voltage Reference Part Context

This part belongs to the LT1790 family of micropower SOT-23 low dropout references. The family combines high accuracy with low power dissipation, utilizing thin-film resistors for precision. The BC suffix indicates the B grade accuracy level, while the S6 denotes the 6-lead TSOT-23 package configuration.
