KA78L08ADTF Application Field and Working PrincipleModern electronic equipment are required to continuously maintain stable supply voltages despite random moments of higher demands. The KA78L08ADTF voltage regulator is specifically designed to provide the regulated voltage to components and circuits. It can be found in personal computers, peripherals and instrumentation, multimedia, communication and automotive systems.The KA78L08ADTF is a three-terminal positive voltage fixed regulator with internal current limiting, thermal shut-down, and safe area protection. The internal current limiter and thermal shut-down prevent the device from being damaged due to a short circuit or overloaded circuit. The regulator uses advanced BiCMOS technology for lower power consumption and improved transient response.The KA78L08ADTF is designed with a precise output voltage of 5V, an output current of 800mA, and a wide input voltage range of 4-25V. It also features an adjustable voltage reference, allowing for output voltage adjustment as needed. The KA78L08ADTF works with a reliability level guaranteed by a high voltage tolerance and a low temperature coefficient. It works on the same basic principle as other voltage regulators: to maintain a steady output voltage regardless of any fluctuations in the input supply. An internal error amplifier generates a voltage relative to the reference voltage, and this signal is compared to the output voltage. Depending on if the output voltage is greater or lesser than the reference voltage, current will be allowed out of the output through either an N-channel or P-channel MOSFET. As the output voltage is adjusted up or down, the feedback voltage changes, regulating the output voltage. The KA78L08ADTF is an ideal solution for embedded computer products requiring low power consumption, as it can support up to 800mA while remaining highly efficient. Additionally, its wide input voltage range, together with its adjustable voltage reference, makes it the perfect solution for applications that require variable voltage outputs.
