The L78M24CV Linear Voltage Regulator is a PMIC voltage regulator designed to provide 24V output in systems that require a variety of operating voltages. It is designed to satisfy general-purpose power module applications, including telecommunications systems, computers, instruments, distributed power modules, etc. The L78M24CV is a 78V input voltage regulator, with a low dropout voltage of 1.1V and 2A output current capability. The adjustable voltage ranges from 5V to 24V.

The main feature of the L78M24CV is its range of integrated protection features, including overtemperature protection, output over-current protection, output over-voltage protection, reverse input polarity protection and power input overcurrent protection. This enables a system designer to easily protect against various operating conditions, which can reduce the risk of system-level damage or failure. The L78M24CV also includes additional features such as reverse-battery protection and overcurrent-limiting for additional system protection.

The working principle of the L78M24CV is based on a series of designs known as Linear Voltage regulators. Linear Voltage Regulators operate by maintaining a constant voltage output in the presence of varying input voltages or fluctuations in load current. The regulator monitors the output voltage and compares it to its internal reference voltage, makes necessary adjustments to maintain the output voltage within a given tolerance. The output voltage is maintained by adjusting the duty cycle of the regulator, which regulates the on/off switching of the P-Channel MOSFET. This is done using Pulse Width Modulation (PWM) with a fixed switching frequency.

The L78M24CV also provides good efficiency, with up to 90% efficiency over a wide input voltage range. This means that the design is less sensitive to load and line variations, and is capable of delivering higher output power.The device provides a low noise operation, with a noise level of less than 10mV RMS at 10kHz.

The L78M24CV is capable of generating up to 2A of current, making it suitable for applications such as motor control circuit, power supply circuits, etc. It is also a highly reliable device, with a maximum power dissipation of 7.5W, a temperature range of -40°C to + 85°C and is safety compliant with the various international standards.

In summary, the L78M24CV Linear Voltage Regulator is a versatile solution for providing reliable voltage regulation in a variety of applications. Its range of integrated protection features, excellent efficiency and low noise operation make it ideal for a wide range of general purpose power module needs. Additionally, its reliability, temperature range and safety compliance make it a great choice for a reliable and safe voltage regulation solution.
