Introduction

The L7824ABV is a fixed output linear voltage regulator commonly used in power management integrated circuits (PMICs). It is able to be used for a wide range of applications due to its ability to maintain a stable output voltage even under varying load conditions. This device is also capable of regulating negative as well as positive supplies providing not only increased functionality but also increased energy efficiency.

L7824ABV Application Field

The L7824ABV can be used in a variety of applications including the power conditioning of electronic devices, providing precise voltage supplies, stabilizing the output voltage of electronic circuits and supplying regulated voltage to monitors and other types of electronic equipment.

This device is used in a wide range of applications like in cellular phones, precision instruments, process control systems, electronic meters, and any other applications requiring high precision and reliability in power supply regulation.

The L7824ABV can also be used in portable and battery powered systems, such as laptops and hand-held devices, due to its high efficiency and low power consumption. The device is designed to be used in high frequency operations, making it ideal for designs with low voltage operation and high accuracy or precision.

L7824ABV Working Principle

The L7824ABV is a three pin voltage regulator that uses an external voltage reference and an output voltage setpoint to regulate its output voltage. A bias resistor, R1, is connected between pins 1 and 3. The device functions by comparing the output voltage (V_OUT) to internal reference voltage (V_REF). If the output voltage reaches the reference voltage, the device shuts itself off to prevent any further increase.

The device also has an output voltage trim capability, by means of external resistors, allowing adjustment of the output voltage in small increments. This adjustable output voltage is useful in applications where the input voltage fluctuates periodically and has to be regulated accurately.

The L7824ABV is a linear regulator, meaning it operates by linear control of the output voltage, dissipating power as heat. This makes the device ideal for applications with low to medium current requirements. The device is also able to provide improved regulation, as it works over a wide temperature range.

Conclusion

The L7824ABV is a three pin voltage regulator designed for high precision, low power systems. This device is suitable for applications that require stable output voltage even under varying load conditions and due to its high efficiency and low power consumption, it is also popular in portable and battery powered systems. The device is easy to use and can be adjusted to provide precise output voltages through the use of external resistors. This makes the L7824ABV a great choice for power management applications.
