The AN79L24M is a Linear Voltage Regulator of the Power Management Integrated Circuit (PMIC) family, which can be used for both small and large current applications. This device is especially suitable for applications with a limited amount of available space, such as portable electronics and computing systems. It can also be used in automotive applications and industrial automation systems.

The main function of the AN79L24M is to convert the input voltage to a regulated output voltage. This device can be used to provide regulated power to electronic components in a variety of conditions, such as voltage drops due to long cable runs, or temperature fluctuations. It can also be used to protect against over-voltage and under-voltage conditions.

Operating Principle

The heart of the AN79L24M Linear Voltage Regulator is its fixed output voltage regulator circuit. This circuit consists of two transistors and two resistors. The transistors are connected to the input voltage source. The resistors are connected between the input and output of the circuit. This configuration allows the device to keep the output voltage at a constant level, even if the input voltage varies.

The AN79L24M also contains an enable control pin. This pin allows the user to control the voltage regulation process by setting the enable pin either high or low. While the enable pin is high, the regulator will operate, and the output voltage will be held at a constant level. When the enable pin is low, the regulator will be disabled, and the output voltage will no longer be held at a constant level.

The AN79L24M also includes a power-on reset circuit. This circuit is used to reset the device when it is powered up. This ensures that the output voltage is always held at a constant level after power up.

Application Fields

The AN79L24M is mainly used in portable electronic devices and computing systems. This device provides an efficient and low-cost solution for providing regulated power in these applications. It can also be used in automotive and industrial applications, where it provides high efficiency, ruggedness, and high current capability.

The AN79L24M is particularly useful in applications where there is a limited amount of available space. This device can be used to provide efficient and regulated power even in situations with long and/or multiple cable runs, or in cases where the ambient temperature is changing.

Conclusion

The AN79L24M Linear Voltage Regulator is an efficient, low-cost solution for voltages regulation in both small and large current applications. This device can be used in a variety of conditions, and is particularly useful in applications with limited available space and long cable runs. The power-on reset circuit provides additional safety, ensuring the output voltage is always held at the desired level after power up. The AN79L24M can be used in portable electronics, computing systems, automotive applications, and industrial automation systems.
