Working Principle

The TPS7A7100RGWR linear regulator operates by using a resistive divider and feedback circuitry to monitor a voltage reference and maintain a constant output voltage. The output voltage is determined by two external resistors that create a voltage divider between the regulated output voltage and ground. When the load current increases, the output voltage is typically drawn down below the desired output voltage, and this triggers a feedback loop that causes the control circuit to increase the bias current to the pass device, thus compensating for the change in load current and maintaining the desired output voltage.

The TPS7A7100RGWR regulator is designed to provide a low-noise output voltage, with an exceptional PSRR of up to 91 dB. This is achieved by using an advanced topology that eliminates the effect of power supply noise on analog signals, ensuring a clean and stable power supply for sensitive components. The device also features low quiescent current, low temperature coefficient, and a wide input voltage range, making it ideal for a wide range of applications.
