TPS3305-25DGN

The TPS3305-25DGN is an integrated circuit (IC) designed and manufactured by Texas Instruments. TPS3305-25DGN belong to the class of PMIC - Supervisors, specially created for low-dropout voltage regulator supervisors applications. It is best known for its low operating current, low operating voltage, and low shutdown current. It is a simple, cost-effective, and reliable solution to ensure the safety of power systems.

The TPS3305-25DGN has an array of wide-ranging applications. In particular, its use for low-dropout voltage regulator supervisors is quite popular. Low-dropout voltage regulators are utilized in a variety of settings, such as consumer electronics, automotive, computer systems, etc. The low-dropout voltage regulator works by providing a low voltage output despite its high input voltage, thereby eliminating the need for excessive loss. TPS3305-25DGN ensure the safety of supply systems by providing regulated input voltage and accurate output voltage. In other words, it is a reliable voltage-monitoring solution that sets up a threshold voltage to ensure the best operation of the low-dropout voltage regulator.

Apart from that, the TPS3305-25DGN is also highly favored for its high accuracy of 0.8V to 5.5V, fast power-on-reset response time of 2 mS, and low operating current of 3.5S (maximum). The power requirement for the TPS3305-25DGN is even lower than any other supervisor in the industry. Also, the TPS3305-25DGN has excellent surge protection which helps to protect valuable components from unexpected power spikes or surges. Additionally, the TPS3305-25DGN is an excellent choice for critical applications as it provides optimal reliability and rugged robustness.

The TPS3305-25DGN integrates a 10 mA low-dropout voltage regulator with a 1.6V to 5.5V power supply and a microprocessor supervisor. When there is an input voltage lower than the threshold voltage, the low-dropout voltage regulator turns off and immediately shuts down the power supply. Meanwhile, the microprocessor supervisor will continuously send a reset signal to a microprocessor to prevent it from taking any unexpected or erroneous action due to the power supply failure. As soon as the input voltage is back to normal, the low-dropout voltage regulator will turn on and provide normal output.

The TPS3305-25DGN also offers high accuracy, fast power-on-reset (POR) response time and fast fault-protection response time. It ensures that the system is stable and will not encounter any sudden power failure. Additionally, it can be programmed through the digital power mode setting pins and the external capacitor-based filter circuit. A threshold pin is provided to manually adjust the threshold voltage. It also provides 25 millivolt resolution. Overall, the TPS3305-25DGN is the ideal supervisor solution for low-dropout voltage regulators and power supply systems.

The TPS3305-25DGN offers a range of advantages for its users. It can be widely used for low-dropout voltage regulator supervisors, especially in consumer electronics, automotive, and computer systems. It has a low operating current and voltage, low shutdown current, and excellent surge protection. Additionally, it provides fast power-on-reset and fault-protection response times. This makes the TPS3305-25DGN a reliable and cost-effective solution for various power systems.
