The KA79L15AZTA is a three-terminal voltage regulator. It is a linear, low-dropout (LDO), n-channel SOT-23 package, manufactured by ON Semiconductor. The LDO regulator is commonly used in devices like personal computers, notebook computers, game consoles and other digital equipment. It is suitable for a wide range of applications, including medical, safety and automotive.

The KA79L15AZTA is used to provide steady and reliable power supply regulation to keep the device running smoothly. It is designed to provide a wide output voltage range, from 2.8V to 18V. The output current is adjustable from 0A to 1A and the output power is 4W maximum. It also features short circuit protection, thermal overload protection and reverse current protection.

The KA79L15AZTA is designed for low noise operation, fast transient response, high line regulation and low output voltage ripple. The easy-to-adjust output voltage and current setting is also a feature of this voltage regulator. The leakage current is very low, and it has a high operating temperature range from -40 °C to +85 °C.

The working principle of a linear voltage regulator is straightforward. It uses an input voltage (Vin) to adjust the output voltage (Vout) by controlling the amount of current that passes through an internal pass transistor. The voltage regulator acts like a variable resistor, which limits the current flowing so that the voltage remains at an optimal level. The feedback control loops of the regulator continuously adjusts the characteristics of the internal pass transistor, so that it can maintain the desired output voltage.

The KA79L15AZTA is an ideal choice for applications that require a reliable source of low-noise, adjustable voltage and current. It is suitable for automotive, industrial, consumer, and medical systems. It is also suitable for other general-purpose applications, combining low voltage and low drop-out adjustable output for microprocessors, audio amplifiers, and many other applications.
