TPS78628KTTRG3 is a 3A high-current, low-dropout linear regulator with adjustable output voltages from 1.2V to 5.5V. It is a member of the Texas Instruments TPS786 family of high-current, low-dropout voltage regulators that feature low quiescent current, fast turn-on time, and extremely low dropout voltage. The TPS78628KTTRG3 is ideal for applications requiring a low-cost, high-current regulator with a wide input voltage range and adjustable output voltage. Its small package size, high current capability, and low dropout voltage make it the perfect choice for a wide range of applications.

TPS78628KTTRG3 is designed to provide a single output adjustable voltage regulator with low dropout voltage, fast turn-on time, and low quiescent current. It features an adjustable output voltage range of 1.2V to 5.5V and a wide operating temperature range of -40°C to +125°C. The maximum current capability is 3A which is suitable for a wide range of battery-powered applications. In addition, the low dropout voltage of 170mV at 3A ensures that the output voltage remains correctly regulated even when the input voltage drops. It also has short-circuit protection and system fault protection to ensure safe operation. Other features include reverse battery and transient protection, overvoltage shutdown, and thermal shutdown.

The working principle of the TPS78628KTTRG3 is based on the voltage division principle. It uses an NPN pass transistor to supply current through a divider resistor network. The output voltage is set by the divider voltage ratio, which is established by the resistor values of the divider. The voltage reference adjusts the output voltage via an internal control loop which compares the output voltage to the reference voltage. The regulation loop then adjusts the bias current driven into the pass transistor to maintain an accurate output voltage.

The TPS78628KTTRG3 is ideally suited for applications such as power supplies and converters, portable electronics, automotive applications, and industrial control systems. It is also suitable for shop or hobby level robotics, energy management systems, medical devices, point-of-load and power modules, instrumentation systems, and building automation systems. With its high output current capability, wide range of output voltages, low dropout voltage and low quiescent current, the TPS78628KTTRG3 is an excellent choice for a wide range of applications.
