The KA7808ETSTU is a part of a Type 78 linear voltage regulator series manufactured by KA7808ETSTU. It is a three-terminal, voltage-regulator IC, which provides a variety of features including high output current and low on-resistance. This makes it an ideal choice for applications that require a high precision control of low input voltages with low quiescent current. This device is made up of an advanced monolithic CMOS or logic-level compatible design, which provides an efficient and effective method of delivering voltage management solutions in discrete and small form-factor packages.

The KA7808ETSTU is designed to regulate a voltage source from 3V to 45V. It has an adjustable current limit and can support up to 8A of output current. Due to its high efficiency, it can provide up to 98% load regulation and output accuracy. Its power supply rejection is also higher than most other linear regulators, making it ideal for applications that require low noise and stable characteristics.

The KA7808ETSTU’s regulator is based on the conventional linear series regulator with a feedback loop which senses the output voltage and adjusts the input voltage to maintain regulation. The feedback is provided by the differential amplifier circuit, which compares the output voltage to the reference voltage. The reference voltage is derived from a band gap reference circuit. The output voltage is then fed back to the amplifier stage to increase or decrease the width of the output range.

The KA7808ETSTU’s external components include a series resistor to set the current limit, and a capacitor or diode-capacitor combination across the output terminals to limit output ripple. The input current limit is typically set to 1A. The device also includes a thermal shutdown feature, which protects it against over current conditions. The device also includes an overtemperature shutdown feature, which restricts the output voltage when the temperature of the device exceeds the specified temperature range.

The KA7808ETSTU is suitable for use in a variety of applications, such as motor control, microprocessor/microcontroller power supplies, instrumentation, medical instrumentation, portable lighting, and many other industrial and automotive applications. It has a low dropout voltage and low quiescent current and can operate with input voltages as low as 3V. Its wide adjustable output voltage range and tight output voltage accuracy make it an ideal choice for applications requiring voltage regulation.
