The TPS79912DDCR is a high-efficiency linear regulator with less than 150 mV of drop voltage at 5.0A. It is primarily used for high current, low-voltage power supply applications such as processors, FPGas, and other power-sensitive loads. Its high efficiency and low drop voltage makes it an ideal choice for applications where space is limited and battery life must be maximized.The TPS79912DDCR has a wide input voltage range from 1 V to 6 V, adjustable output voltage from 0.6 V to 3.6 V, and output current up to 5 A. It offers the convenience of a low-cost, fast-transient response and low-dropout mode of operation. The device features thermal shut-down protection and over-current protection.The TPS79912DDCR consists of a voltage reference, an error amplifier, a driver, and a MOSFET. The reference section provides a low temperature coefficient and high accuracy. The error amplifier compares the output voltage to the reference to produce the control signal to the MOSFET driver. The driver then provides the necessary gate drive to control the current flow through the MOSFET.The MOSFET is used to regulate the current through the load. The MOSFET also operates in diode mode when the output voltage falls below the input voltage. In this mode, it allows the sub-supply to float at a voltage lower than the main supply in order to reduce power dissipation.The TPS79912DDCR is designed to work with a wide range of application scenarios and can be used for processor cores, FPGAs, MRAMs, ASICs, and other power-sensitive devices. It is suitable for automotive and industrial applications due to its robust design.In order to maximize efficiency, the TPS79912DDCR employs an adjustable high-bandwidth voltage loop. This feature allows the user to dynamically adjust the loop transmission ratio of the regulator to the application’s changing load conditions. This improves efficiency, reduces power loss, and provides outstanding transient responses for changing loads.The TPS79912DDCR is built on a low-noise CMOS process and has a low ripple output voltage. It also reduces EMI emission on the output line. Furthermore, the device has a low start-up current and low quiescent current.Overall, the TPS79912DDCR is a high-efficiency linear regulator that is ideal for high current, low-voltage power supply applications. Due to its wide input voltage range, adjustable output voltage, and adjustable output current up to 5A, it is suitable for a wide range of applications. The features of its low-cost, fast-transient response, low-dropout mode of operation, and adjustable high-bandwidth voltage loop make it an ideal choice for applications where space is limited and battery life must be maximized.
