MC7918CT Application Field and Working Principle

MC7918CT is a voltage regulator of the linear PMIC (Power Management ICs) family from ON Semiconductor. Manufactured in an 8-pin plastic DIP package, this device is especially designed to maintain a constant output voltage. This regulator is a three-terminal adjustable device that features a low drop-out voltage, making it ideal for power supply applications.

Features

• Input voltage range of up to 25V
• Capable of delivering up to 0.2A of output current
• Maximum drop-out voltage of 4V
• Integrated over temperature protection
• Has a high-temperature shut-down (HTSD) feature
• Highly accurate output voltage regulation

Applications

The MC7918CT voltage regulator is designed for use in power supplies, battery chargers, industrial, automotive and computing applications. Its low drop-out voltage allows the device to be used with input voltages up to 25V, enabling it to be used in applications with wide input voltage variations. In addition, it features a high reset temperature, which increases the operating temperature range of the regulator, making it an ideal choice for industrial applications.

Working Principle

The MC7918CT is a linear voltage regulator, which operates by maintaining a constant voltage output, regardless of changes in input voltage and/or load current. It achieves this by amplifying the difference between its output voltage and the reference voltage level, to adjust its output voltage. The reference voltage is usually set by the internal circuit and is constant. The amplified difference is then used to increase or decrease the output current and hence the output voltage.

The MC7918CT is designed to deliver high current at low drop-out voltages, which makes it ideal for use in mobile and computing applications. The device is manufactured from an 8-pin plastic DIP package. This package is designed to operate over a wide range of temperatures, making it suitable for use in high temperature applications.

The MC7918CT also features programmable protection features such as over-temperature protection, HTSD (high-temperature shut down) and over-current protection. This ensures the device remains safe even under demanding or adverse conditions.

The MC7918CT is an ideal choice for a wide range of power supply applications, due to its low drop-out voltage, wide input voltage range and programmable protection features. Its high current delivery makes it suitable for applications that require higher current.
