AP1184K5-25L-13

Introduction to AP1184K5-25L-13

The AP1184K5-25L-13 is a low dropout linear voltage regulator, providing a regulated voltage output of 5V with a maximum output current of 25mA.

It is designed to be used in systems where a minimum of power is available, allowing the regulator to maintain its output voltage with the presence of a very low dropout voltage, typically of 0.34V at 25mA . This makes it ideal for supplying microcontrollers and other precision circuitry with a regulated voltage over a wide range of load currents.

Application Field and Working Principle of AP1184K5-25L-13

The AP1184K5-25L-13 is designed for use in electronics components with low power requirements including microcontrollers and memory ICs, consumer audio and video equipment, security and alarm systems, portable instruments, and many other applications.

The AP1184K5-25L-13 works by taking an input voltage and using an internal regulator to hold the output voltage level steady. The internal regulator is a linear type and uses a resistor divider network on the input side to monitor the output voltage level compared to a fixed reference voltage level. As the load current changes, the regulator adjusts itself accordingly, maintaining the same ratio between the input and output voltages.

As no active power devices are used in the circuit, the regulator operates as a linear mechanism, as opposed to a switching regulator, which uses an oscillator to generate a pulse-width switching frequency.

The low dropout voltage of the AP1184K5-25L-13 is achieved by a special design which uses a low noise P-channel MOSFET in series with the regulator\'s output. This allows the regulator to maintain its output voltage with very low input-output differential voltages, allowing the device to be used in environments with limited power supplies.

The AP1184K5-25L-13 also has an internal thermal shutdown system which is designed to protect the device from overheating. When the internal temperature of the regulator rises above the pre-set temperature limit, the thermal shutdown system automatically shuts down the regulator, protecting it from further damage.

Conclusion

The AP1184K5-25L-13 is a low dropout linear voltage regulator specifically designed for low power applications. Its low dropout voltage allows it to maintain a regulated output voltage over a wide range of load currents, making it ideal for supplying microcontrollers and other precision circuitry with a regulated voltage. The device also incorporates a thermal shutdown system for increased safety and reliability.
