SPX1585AT-L-3-3/MTR

SPX1585AT-L-3-3/MTR Application Field and Working Principle

The SPX1585AT-L-3-3/MTR is a voltage regulator in the Programmable Linear Voltage Regulators (PLVR) family of products from SIPEX Corporation. It is specifically designed to provide low-cost and efficient power regulation for a range of applications.

The SPX1585AT-L-3-3/MTR is a monolithic 500V power supply regulator that features a low-dropout (LDO) design and adjustable output voltage. It was designed to be used in such application fields as automotive and industrial systems with limited input voltage of up to 12V, and output voltage ranging from1.5V to 3.3V.

The SPX1585AT-L-3-3/MTR boasts a number of features that make it an ideal choice for power regulation in a range of applications. It is equipped with an MTPOT (multi-turn power-on-time) circuit that provides fixed, precise, and fast regulation of output voltage, current and temperature. It also has a low quiescent current of only 9mA, making it very efficient in providing regulated power. The SPX1585AT-L-3-3/MTR also provides feedback to its own internal temperature sensors, allowing it to adjust the output voltage in relation to both the temperature and the current draw from the power supply, resulting in better overall performance.

The SPX1585AT-L-3-3/MTR also contains an adjustable over-current fault protection (OCFP) circuit. This feature allows the user to set the maximum current output, meaning it will automatically shut down if the current exceeds the pre-defined limit. This is important, as it helps to ensure the protection of both the device and the components connected to it.

Working Principle

The SPX1585AT-L-3-3/MTR is a very efficient power regulator and operates by using an LDO (Low Dropout) design. In an LDO, the load is controlled by a voltage regulator that allows the output to remain constant regardless of the load. This is done by regulating the amount of current passing through the regulator, which in turn allows the voltage output to remain fixed regardless of any changes in load.

In order to ensure the reliable and accurate operation of the power supply, the SPX1585AT-L-3-3/MTR features multiple input and output protection features. The output is protected by both over-voltage and over-current protection circuits, while the input voltage is protected by an under-voltage cut-off circuit. These features ensure protection to the power supply and its components in the event of any irregular voltage or current draw.

The SPX1585AT-L-3-3/MTR is a reliable and efficient power regulator, providing adjustable output voltage and over-current protection. It is suitable for automotive and industrial systems, with input voltage up to 12V, and output voltages of between 1.5V and 3.3V. Its low quiescent current makes it highly efficient, while the added protection features increase both reliability and safety.
