KD1084AV33 Application Field and Working Principle

The KD1084AV33 is a voltage regulator from Mitsubishi Electric Corporation and is a member of a linear voltage regulator group designed for use in automotive, industrial and telecom applications. The regulator is rated for output current up to 1.5A and an input voltage up to 20V. It offers an output voltage setting range of 0.95V to 13.2V, making it suitable for applications such as charging, DC/DC converter operation and LED driving. The KD1084AV33 also features an adjustable over-current protection circuit which helps protect the load from current overload.

In order to understand how the KD1084AV33 works, it is necessary to understand first the working principles of linear voltage regulation in general. When a voltage source is driven across a load, the voltage stability of the source depends on the load\'s current demand. If the current demand is high, the voltage drops, and vice versa. In order to compensate for this voltage drop and make sure that the output voltage stays stable, a voltage regulator is used. A linear voltage regulator works in a similar way, but instead of relying on a constant current source, it uses negative feedback to modify its output voltage depending on the input voltage and load current.

The KD1084AV33 implements a Linear Voltage Regulator (LVR) circuit with three terminals – an input terminal, an output terminal, and an enable terminal. The input voltage is applied to the input terminal which is then regulated by the internal pass element to the output terminal. The enable terminal is used to enable or disable the regulator depending on the load requirements. When disabled, the output voltage is pulled to ground, effectively disabling the regulator.

The KD1084AV33 features an integrated temperature compensation circuit that adjusts the output voltage depending on the temperature, providing better regulation across a wider range of temperatures. This circuitry also ensures that the regulator can accurately maintain the output voltage up to a predetermined temperature. The thermal shutdown circuit prevents the regulator from straying too far from the specified output voltage. This can prevent damage to sensitive components which may be connected to the regulator.

The KD1084AV33 also offers short circuit protection, providing more protection for the load it is powering. The regulator also features a built-in current limit to protect the device from excessive input current. Finally, the device also offers a built-in noise filter to reduce switching noise during operation.

The KD1084AV33 is suitable for automotive, industrial and telecom applications, and is ideal for applications such as step-down DC-DC converters and LED drive circuits. Its adjustable current limit, temperature compensation, and over-current protection circuits make it a robust and reliable solution for many applications. Its small package size and low quiescent current also make it a great choice for applications where space is limited.
