Working principle

The TS2940CZ50 C0G is a 3-terminal negative voltage regulator. It is the basic building block of a power management circuit, and its principle is the same as any other voltage regulator, regardless of its positive or negative polarity. It is designed to be connected to a power source, such as a battery, and provide a constant, steady output voltage to the load.

The TS2940CZ50 C0G uses P-channel MOSFETs to regulate the output voltage. The MOSFETs are sourced by the input voltage and connect the load side with the ground. The voltage is then regulated by the two N-type transistors, which are connected to the load side and act as the current limiting elements.

The regulator is extremely efficient due to the use of a feedback circuit. The feedback circuit samples the output voltage and compares it to a precision reference. If the output voltage is too high, the feedback loop sends a signal to the control terminal to decrease the gate voltage of the MOSFET, reducing power to the load. Conversely, if the output voltage is too low, the feedback loop sends a signal to increase the gate voltage of the MOSFET, increasing power to the load. This cycle continues until the output voltage is stabilized.

Conclusion

The TS2940CZ50 C0G is an excellent choice for applications requiring a negative voltage regulator with a wide input voltage range, adjustable output voltage, and low power consumption. Its small size and light weight make it ideal for portable applications. Its flexible protection and built-in protection features make it highly dependable in all kinds of applications that require an adjustable, low-dropout negative voltage regulator.
