Introduction to TPS79933YZUT

The TPS79933YZUT is a low-dropout (LDO) three-terminal linear regulator, specifically designed for low voltage, low quiescent current applications. It is simple to use and provides excellent line and load regulation, combined with high efficiency. It\'s designed to reduce board space, cost, and complexity by eliminating multiple discrete components. It has a maximum output voltage of 3.3V, and a maximum input voltage of 6.5V.

Functionality of TPS79933YZUT

The TPS79933YZUT is a low-dropout regulator that maintains a constant output voltage regardless of changes in the input voltage and load current. It is designed to remain free from short-circuit conditions, providing long-term protection for the system in over-current applications. The maximum output voltage can be adjusted from 2.5V to 5.5V in 1.5V steps, making it suitable for many applications. Furthermore, the dropout voltage is very low, as little as 75mV, allowing designs to achieve high efficiency and low power consumption. The device also features advanced protection features, including over-temperature protection and reverse current protection.

Applications of TPS79933YZUT

The TPS79933YZUT is designed for a wide range of applications, including: portable and mobile device power supplies, automotive, LED lighting, aerospace systems, and automotive start-ups. It is ideal for low voltage applications, such as powering electronic systems up to 3.3V, and is suitable for applications that require low quiescent current, such as battery-powered devices. The low power consumption, low dropout voltage, and wide input voltage range make it suitable for automotive start-up applications, where reliability and efficiency are critical.

Working Principle of TPS79933YZUT

The TPS79933YZUT LDO voltage regulator works based on a principle known as Voltage Regulation. This means that it measures the difference between the input voltage and the output voltage and adjusts the output voltage to maintain the difference between them, providing a regulated and reliable output voltage. This is achieved by controlling the quiescent current, to maintain a preset reference voltage at the non-inverting input of the amplifier. The quiescent current and output voltage are monitored by an external feedback loop, allowing the device to regulate the voltage to within its programmed limits.

Conclusion

The TPS79933YZUT is a low-dropout linear voltage regulator specifically designed for low voltage, low quiescent current applications. It is simple to use, extremely efficient, and has protection features such as over-temperature protection and reverse current protection. The input voltage range and output voltage range are adjustable, making it suitable for a wide range of applications, from portable devices to automotive start-ups. It is based on the Voltage Regulation principle, whereby it monitors the input and output voltages and adjusts the output voltage to maintain a difference between them.
