TXS75218QPWPR is a linear voltage regulator used in portable and embedded applications. It is designed to provide well-controlled adjustable output voltages and high current output with tight regulation. It is suitable for a variety of voltage regulation applications including power supplies, portable appliances, industrial systems, automotive systems, and lighting electronics.
The output voltage can be adjusted from 0.9V to 9V using the external resistor (R1 and R2) connected between the FB pin and GND. The feedback voltage, VFB, is regulated to ensure a regulated output voltage. The compensation network (C1, C2, C3) ensures stability and transient response for the regulator. The internal current limiting of the device will limit the output current to the rated value of 4A and protect the device from over-current conditions. In addition, the built-in thermal shutdown and overvoltage protection will protect the device in case of over temperature and over voltage conditions.
