S-11L10C23-M5T1U

Linear voltage regulators are one of the most essential electrical components which are used in various digital and analog electronic devices. The S-11L10C23-M5T1U is a low-cost linear voltage regulator provided by Microchip Technology, Inc.

Features

The S-11L10C23-M5T1U is an adjustable linear regulator which can provide a regulated output voltage from 0.8 to 11V with a current capacity of up to 10 A. It has an operating temperature range of -40°C to +125°C and a low power dissipation of just 0.18W at 10A. It also features a maximum voltage drop of 0.1V at full load, which is ideal for low noise and low power applications. Additionally, the S-11L10C23-M5T1U has a low quiescent current of just 5μA, which makes it suitable for use in battery-operated and portable devices.

Application Field

Due to its low noise and low power dissipation, the S-11L10C23-M5T1U is well suited for a range of battery-operated and portable devices such as laptops, portable media players, digital cameras, and other electronic devices. It can also be used in electronic circuits with high current requirements such as automotive electronics, hot-swappable power supplies, medical equipment, and industrial automation systems.

Working Principle

The S-11L10C23-M5T1U works by applying a variable voltage across the sense terminal and setting the voltage across the sense terminal to match the desired output voltage. The variable voltage is generated by an internal PNP transistor which is connected between the output and the sense terminal. The voltage generated by the internal PNP transistor is then regulated by an internal error amplifier. Once the voltage across the sense terminal is set, the error amplifier adjusts the internal PNP transistor to maintain the output voltage constant.

The S-11L10C23-M5T1U also features protection circuits to protect the device from overcurrent, overvoltage, reverse current, and over-tempaerature conditions. The overvoltage protection circuit detects when the input voltage is too high and shuts down the PNP transistor, which in turn prevents the output voltage from rising too high. Additionally, the over-temperature protection circuit monitors the device\'s temperature and reduces the current through the PNP transistor if the temperature rises too high. This helps prevent damage from overheating.

Conclusion

The S-11L10C23-M5T1U adjustable linear voltage regulator is a low-cost and efficient device which is ideal for a range of battery-operated and portable electronic devices. It is capable of providing a regulated output voltage from 0.8 to 11V with a maximum voltage drop of 0.1V at full load. It also features protection circuits to protect the device from overcurrent, overvoltage, reverse current, and over-tempaerature conditions. It is an ideal choice for anyone looking for a low-cost and efficient linear voltage regulator.
