TPS75933KC Application Field and Working Principle

PMIC - Voltage Regulators - Linear

The TPS75933KC is a Standard Voltage Power Management Integrated Circuit (PMIC) designed to monitor, control, and protect system power, including battery management. It belongs to an extensive family of Linear Voltage Regulators (VR) and Switching Regulators (SR) from Texas Instruments. With its low power consumption, it is especially suitable for portable electronic systems and can be used for a range of applications, such as mobile phones, PDAs, digital cameras and toys.

The TPS75933KC is a low-dropout (LDO) Linear Voltage Regulator with high power quality, fast transient response, and low output noise, offering a fixed output voltage of 3.3 Volts. With a range of features, it delivers a very efficient power management solution. The device contains two high performance fast-transforming low dropout linear voltage regulators capable of delivering up to 1A of continuous output current. The device also offers an adjustable output voltage of up to 5.5V, a low quiescent current of 9 μA, and fast settling time. Additionally, the device provides an overvoltage protection capability and can provide output current limiting.

The TPS75933KC is designed to maintain output voltage accuracy even as the voltage across its input terminals rise and fall. It uses a control loop that senses the output voltage, compares it to a power reference, and adjusts its internal current sources to maintain the desired output voltage. The device is protected from over-temperature and has an active discharge circuit to quickly discharge the output capacitor when the supply voltage is removed. This feature ensures safe system operation and improved system reliability.

The TPS75933KC is characterized by its low power consumption, high efficiency, and fast transient response. It draws an ultra-low quiescent current of 9 μA when enabled, which can significantly extend the system’s battery life. The device features a fast transient response of 3.3µs to reduce power spikes during sudden load changes. The device also provides output current limiting protection to protect your system against short-circuits.
