Working Principle
The TPS7250QP linear regulator works by detecting the input voltage, then comparing it with the reference voltage. If the difference between the two voltages is greater than the voltage reference, the regulator turns on. When the difference drops below the reference voltage, the linear regulator turns off, thus maintaining a steady output voltage.
The regulation process is facilitated by the integrated transconductance amplifier, which acts as an error amplifier that amplifies the difference between the input and output voltages. The amplifier is capable of controlling the width of the output voltage pulse, and thus the desired output voltage.
The TPS7250QP is designed to provide a precise output voltage with minimal noise. To achieve this, it requires a high-impedance output filter, which is integrated onto the regulator. This filter reduces output noise and prevents the output voltage from oscillating.
Conclusion
The TPS7250QP is a low-cost, low-power linear regulator for various PMIC applications. It provides excellent power delivery and low noise, and its low-dropout feature allows for efficient operation. Its high accuracy and low output voltage ripple ensures a stable output voltage, and it is integrated with a high-impedance output filter to reduce noise and prevent output voltage oscillation. The TPS7250QP is an excellent choice for low-noise, high-efficiency voltage regulation.
