Working Principle of TPS71828-28YZCR

TPS71828-28YZCR is a voltage regulator that uses a linear series pass transistor to regulate the output voltage. The output voltage is regulated by sensing the output voltage and controlling the base current of the pass transistor. The voltage sense of the pass transistor is compared to the internal reference voltage of 1.1 V. If the voltage sense is greater than the reference voltage, the pass transistor is turned off, reducing the output voltage. However, if the voltage connect to the voltage sense is lower than the reference voltage, the pass transistor is turned on and increases the output voltage.The regulator also offers protection from short-circuiting or over-temperature conditions. If the current through the pass transistor exceeds an over-current threshold or if the temperature of the device exceeds the maximum temperature, the pass transistor will be shut off and the output voltage will be reduced to a safe level. This helps to protect the device from damage due to over-current or temperature conditions.

Conclusion

TPS71828-28YZCR is a low-dropout linear voltage regulator which offers a wide range of application fields. It can be used in various computer peripheral, telecom and network equipment, automotive, industrial, and consumer electronics products. The working principle of the regulator is based on a linear series pass transistor, which is regulated by comparing the voltage sense to the internal reference voltage of 1.1 V. The regulator also offers protection from short-circuiting or over-temperature conditions.
