TPS793475DBVRQ1, a linear voltage regulator, is designed to deliver up to 1.5A of output current and offer improved transient performance with higher output drive capability. It is optimized for ultra-low-Iq operation and high-ripple rejection. With a full complement of features, the regulator provides cost effective operation for a wide range of applications.

The linear voltage regulator has several application fields, including Automotive, Cellular Handset, Medical, Industrial and Networking, to name a few. TPS793475DBVRQ1 has been proven in a number of automotive and industrial applications: engine control modules, infotainment systems, monitors, networking systems, power and communications equipment, etc. It is also an ideal choice for powering MCUs and ASICs in them.

The TPS793475DBVRQ1 linear voltage regulator works by comparing the voltage of an external reference voltage with the output voltage of the regulator. When the regulator’s output voltage is too high, current flows from the output to the reference voltage, which is regulated by circuitry that acts as a feedback loop. As the output voltage falls, allowing current to flow back into the output, the error amplifier increases the current flow until the output voltage matches the reference voltage. As the error amplifier senses the voltage difference between the reference voltage and the output voltage, it continuously adjusts the current flow.

The TPS793475DBVRQ1 has a wide input voltage range from 2.25V to 5.5V, and a low drop-out voltage over its required rated output voltage range of 1.5V to 5V. The device also offers enhanced transient response due to an internally controlled p-channel MOSFET, where the voltage is set with an external resistor divider. To optimize the transient response, the CS pin allows the user to provide an external connection to an output capacitor. This improves stability and sense protection for over-voltage conditions.

The TPS793475DBVRQ1 features precise output voltage sequencing ideal for applications such as as power sequencing. It offers sequence start/stop and step up/step down sequencing. The integrated error amplifier, output FET driver, input voltage sensing and precise voltage scaling allows the output voltage to be monitored and controlled. It also provides an enable/disable feature to reduce quiescent current, which is ideal for low power applications.

The TPS793475DBVRQ1 is a versatile, inexpensive and reliable voltage regulator that is well suited for a wide range of applications. The device offers an optimal combination of low quiescent current and high load regulation. It is also highly reliable and offers integrated EMI/RFI filtering to help with system noise suppression. The device is housed in a small 6-pin SOT-23 package, making it ideal for space constrained applications.
