TPS728120150DRVR is a three channel high performance linear regulator from Texas Instruments. It is designed to offer a simpler solution for dc/dc conversion while providing excellent line transient responses, superior power efficiency and fast transient recovery time. The TPS728120150DRVR is available in a high current 3-V supply and offers excellent input, output and line regulation with a maximum input voltage of 28V and adjustable output voltage range of 0.6V to 3V. It also includes an over temperature protection feature and an input supply rejection ratio of more than 80dB   allowing it to work with a wide range of input and output conditions.

The TPS728120150DRVR is specifically designed to address the needs of high performance and low power applications. In particular, it is suitable for low voltage point-of-load (POL) voltage regulation. This makes it ideal for use in applications such as server processors, logic circuits, and networking applications. In addition, it can also be used in embedded designs for dropout control, and in DC/DC converters for high efficiency automatic power management systems.

The working principle behind the TPS728120150DRVR is based on a classic linear regulator topology. It uses a power transistor to regulate the output voltage, a fast-acting reference voltage for sensing, and current limiting and over temperature protection circuitry. The current through the pass transistor is proportional to the voltage gain setting enabling it to maintain a constant output voltage despite variations in input voltage and load current.

The TPS728120150DRVR is configured with two external resistors to regulate the output voltage while the internal output feedback circuitry regulates the output voltage to within 1% accuracy over the entire temperature range. The output voltage can be set between 0.6V and 3V. The current limit is also adjustable via an external resistor and can be set to 250mA, 500mA, 750mA or 1A. In addition, the TPS728120150DRVR also features thermal protection embodied in an internal temperature sensitive circuit which shuts down the regulator in case of an overtemperature condition.

The TPS728120150DRVR is an ideal choice for high efficiency low voltage POL dc/dc conversion applications. It offers excellent line and load transient responses, exceptional power efficiency, and fast reaction times, making it a great choice for designers looking to maximize their system performance.
