Working Principle of the ZSR300CSTOB

The ZSR300CSTOB is a three-terminal linear regulator that maintains a constant output voltage by varying the amount of current that is sunk through two external transistors. The output voltage is determined by the ratio of two external voltage-setting resistors, R1 and R2. By adjusting the values of these resistors, the output voltage can be set from 1.2V to 20V.

The ZSR300CSTOB is designed to maintain a constant output voltage even when the input voltage is changing. The dropout of the device is very low and it remains stable over a wide range of input voltage, so it can be used in applications where the power supply may not be perfectly regulated.

The regulator is able to provide current limiting, over-current protection, thermal protection and under-voltage lockout. It is also capable of providing up to 500mA of output current. The high current capability and low quiescent current makes it suitable for use in many applications where energy efficiency is critical.
