Working Principle

The TCR3DG10 linear voltage regulator works on the principle of controlling current between the input voltage and output voltage. The device consists of an unregulated input voltage, a reference voltage and a feedback loop. The reference voltage is set by a resistive divider, and the output voltage is determined by the ratio of the resistors. The feedback loop is used to regulate the output voltage by sensing a feedback voltage and adjusting the input current accordingly. This ensures that the output voltage is regulated to the desired level.

In order to control over-voltage, the device also has an over-voltage threshold. When the input voltage exceeds this threshold, the device will shut off the output voltage, resulting in a regulated voltage that is lower than the input voltage, but still within the specified range. Additionally, it will also provide protection against over-current by limiting the maximum current that can be sourced or sunk.

Conclusion

The TCR3DG10 is a low voltage linear voltage regulator with a wide range of operating voltages from 6.7V to 10V. It offers excellent protection against over-voltage, current regulation and over-current and can provide an output voltage of up to 10V. It is an ideal solution for battery management and other low voltage applications due to its ability to source and sink current and its wide operating range.
