The LT6654BHS6-3.3#TRPBF is a specialized component belonging to the line of PMIC (Power Management Integrated Circuits) voltage references. These voltage references are responsible for maintaining a steady and precise voltage level in integrated circuits. To understand the application field and working principle of the LT6654BHS6-3.3#TRPBF, it is necessary to first get familiar with voltage references and their general characteristics.

What is a Voltage Reference?

A voltage reference is a component in an Integrated Circuit (IC) that is designed to output a stable, precise and constant voltage level. Voltage references are mainly used for setting performance-critical parameters for the operation of the IC. Examples of critical parameters include but are not limited to: supply voltage and current levels, gain, output impedance, and input-output differential voltage and current thresholds. Voltage references play a major role in power management circuits as they help to maintain precise levels of voltages that are necessary for the correctness and consistency of the power management circuit’s operation.

In order to maintain precision and stability of the voltage level that a voltage reference produces, it is critical that the component is designed with very small tolerance levels. The components within the IC must be maintained within a very precise range of values, often by a factor of a 1% or even 0.1% tolerance (T%). Tolerances this small require a much more precise control of the component’s output characteristics, while at the same time keeping the output’s noise and distortion levels low. This task is taken up by voltage references.
