Working Principle of AN80L32RMS Voltage Regulator
The AN80L32RMS is a linear voltage regulator which comprises of three main components: voltage regulator, error amplifier and pass transistor. The voltage regulator is a series-pass type regulator which works in conjunction with the others to ensure that the output voltage is proportional to the input voltage.
The voltage regulator takes in the input voltage and produces a reference voltage that is compared to a voltage reference window (which is set through the resistors on the regulator). If the output voltage is too high, the error amplifier goes into a high state and turns on the pass transistor to lower the voltage. Conversely, if the output voltage is too low, the error amplifier will turn off the pass transistor and increase the voltage. In this way, the voltage regulator works to regulate the output voltage over a given range.
The AN80L32RMS can also be used with an external low-dropout regulator to reduce output noise and improve efficiency. This type of regulator is typically used when the input voltage is much higher than the output voltage, as the pass transistor will begin to draw more current as the voltage differential increases. By adding the external regulator, the pass transistor can be optimized and the output noise can be reduced.
