Working Principle

The TPS7B6733QPWPRQ1 is a linear voltage regulator that operates using a series of voltage reference, voltage divider and error amplifier circuitry. The device takes in an input voltage and passes it through a voltage reference circuit to set a regulated output voltage. Then, the output of the voltage divider is compared to the reference voltage. If the output is too high, the error amplifier triggers the series-pass transistor, diverting the excess voltage to ground. If the output is too low, the same process occurs in reverse, increasing the output voltage. The series-pass transistor is constantly being adjusted in order to maintain a constant output voltage.

The linear voltage regulator used by the TPS7B6733QPWPRQ1 provides several advantages over switching regulators. For one, linear regulators offer better accuracy and regulation of output voltage. The control circuitry of a linear regulator is also less complex, resulting in fewer components and thus lower cost. Finally, because linear regulators do not use switching or pulse-width modulation, they provide exceptionally low output noise and ripple voltage, which can be beneficial in sensitive electronic systems.
