KA79L15AZBU Application Field and Working Principle

The KA79L15AZBU is a 3-terminal positive voltage regulator designed for a wide range of input voltages and low power applications. The device is a versatile low-dropout linear voltage regulator, ideal for use in mobile phones and other applications where low power dissipation, low noise and low harmonic distortion are the main requirements.

Application Fields

The KA79L15AZBU is suitable for applications where low dropout linear voltage regulation is required, such as:

• Battery-powered systems
• Portable medical equipment
• Portable devices
• Computers
• WiFi, Bluetooth, Zigbee, and LTE communications devices
• Consumer electronics
• Security systems
• Instrumentation

The device has an input voltage range of 1.5V to 10V, output current of up to 300mA and a power dissipation rating of 1W. It is available in several different packages, including the TSOT-23, SOT-23 and SOT-89.

Working Principle

The KA79L15AZBU is a low-dropout linear voltage regulator, which produces a constant, stable output voltage from an input voltage that is within its specified range. It utilizes a PNP transistor in order to sense the input voltage, thus providing very low dropout characteristics. The output voltage is set by the combination of a potentiometer and an internal reference voltage, and is adjustable over a range of 1.2V to 5.0V.

The device has a number of features which contribute to its low power dissipation and low noise output. These include a low-dropout voltage, low output voltage noise and low quiescent current. The device also provides protection against thermal overload, output short-circuit and input overvoltage, and it has built-in over-temperature protection.

In order to maximize the linear regulator\'s efficiency, proper loading should be applied to the input and output of the device. A low ESR capacitor should be used on the output to reduce noise and ripple, while a series capacitor should be placed on the input in order to reduce supply voltage drops.

Conclusion

The KA79L15AZBU is a versatile 3-terminal positive voltage regulator which is ideal for a wide range of low power applications. It utilizes a PNP transistor for low dropout characteristics and offers several features which contribute to its low power dissipation and low noise output. Proper loading should be applied at the input and output in order to maximize the efficiency of the linear regulator.
