The TPS72501KTTT is widely used in a variety of applications. The device is a highly efficient option for powering high-current applications, such as LEDs, LCDs, computer displays and other applications that require current or voltage regulation. The device is also suitable for powering mobile devices and other portable applications.

The Working Principle of the TPS72501KTTT

The TPS72501KTTT is a high efficiency, low noise, advanced linear voltage regulator from Texas Instruments. The device is designed to work with a 3.3V to 28V input voltage range and can deliver up to 1.5A of continuous current in an ultra-low noise operational mode.The device consists of two main components; a positive voltage regulator and a negative voltage regulator. The positive voltage regulator consists of an N-channel power MOSFET, a set of resistors, and a voltage divider circuit. The voltage divider circuit adjusts the voltage output of the device, while the N-channel power MOSFET acts as a current source to limit the output current.The negative voltage regulator consists of a P-channel power MOSFET, a set of resistors, and a voltage divider circuit. The P-channel MOSFET acts as a current source to limit the output current and the voltage divider circuit adjusts the voltage output of the device.The device uses a single feedback resistor to control the voltage output and incorporates a soft-start circuitry which reduces the inrush current. The device is also designed to provide over-voltage protection and auto regulation of the input voltage transient.
