Integrated circuits, known as ICs, are devices made up of many transistors, resistors, capacitors, and other components, all combined in one small package. Power Management ICs, or PMICs, are ICs that are specifically designed to manage and distribute power throughout circuits. PMICs are separated into several categories depending on the type of power performance and function desired. Aclass of PMICs is Voltage Regulators, which can be either linear or switching. Linear regulators are used to provide stablevoltage regulation, even during line and load fluctuations, and are employed in numerous systems such as computers, cell phones, LED lighting and appliances.One particular linear voltage regulator, the S-814A39AMC-BDDT2G, is suitable for applications such as industrial controllers and motor controllers that must use wide-range input voltages and require little noise performance.

Working Principle

The S-814A39AMC-BDDT2G is a self-contained, integrated three-terminal device with a integrated N-channel MOSFET as the pass element linear regulator. This allows the device to regulate input from a wide range of voltages from 14V to 39V. The operating temperature range of -40°C to +125°C, is ideal for many industrial applications. As the output voltage is regulated the current passes through the device steady and constant, reducing power loss and line and load fluctuations. Voltage regulation adapts to the load changes and noise immunity, allowing for a stable power supply even in the most demanding environments.

Inside the S-814A39AMC-BDDT2G are components designed to ensure excellent regulation such as an adjustable bandgap, current limiting, and thermal tracking. The proprietary start-up circuitry provides a stable startuppoint, while the internal circuit design reduces power consumption, resulting in low heat generation. Furthermore, the device is protected against reverse polarity, thermal shut-down, and over-current.
