It provides comprehensive protection features such as over voltage, under voltage and over temperature protection.

Application Field

The TPS7A1010PYKAR is applicable to automotive applications, such as mobile device power management, automotive infotainment, engine control, electronic control units, transmission control and other automotive electronic applications. It is also suitable for industrial applications, including power management, portable instruments, machine tools, industrial electronics, precision machine tools and portable medical devices.

Working Principle

The TPS7A1010PYKAR is an adjustable LDO regulator capable of providing a stable output voltage from 0.7V to 5.5V. It uses a voltage reference that is connected to a voltage divider circuit to set the desired regulated output voltage of the regulator. This regulated output voltage is compared with a feedback voltage derived from the output of the regulator, which is subjected to the load current. To compensate for the discrepancy between the two voltages, the regulator adjusts the output current through its built-in current limit circuit. This adjustment process is repeated rapidly to maintain a stable output voltage.

The TPS7A1010PYKAR is equipped with a constant-on-time overload protection circuit. The circuit senses the increase of temperature caused by the excessive load current, and it turns off the output switch to protect the device from an overload condition. It also features over voltage and under voltage protection to protect the device from unwanted high or low voltage levels.

Conclusion

The TPS7A1010PYKAR is a low-dropout (LDO) programmable voltage regulator that is designed for the industrial and automotive market. It provides an adjustable output voltage, adjustable current limit and constant-on-time over current protection circuit to ensure high reliability and accuracy. The device is suitable for a wide range of automotive and industrial applications, such as power management, portable instruments, and machine tools. The device features comprehensive protection features such as over voltage, under voltage and over temperature protection.The specific data is subject to PDF, and the above content is for reference
