With a maximum input voltage of 20V and a low dropout voltage of 0.55V at full load, this regulator is ideal for a wide range of applications that require a stable and reliable power supply. Its compact TO-263-6 package with five leads and a tab makes it easy to mount on a circuit board, while its enable control feature and over-temperature and reverse-polarity protection make it a flexible and robust solution for demanding applications.
Linear regulators are essential components in many electronic systems, providing stable and low-noise DC voltage to power microcontrollers, sensors, analog circuits, and other components. The TL1963A-25KTTR from Texas Instruments is a high-performance linear regulator that stands out for its low dropout voltage, high output current, and excellent line and load regulation. Let's take a closer look at its features and specifications.
The TL1963A-25KTTR is a positive fixed voltage regulator that can deliver up to 1.5A of current at a fixed output voltage of 2.5V. This makes it an excellent choice for applications that require a stable voltage source with a low dropout voltage, such as battery-powered devices, embedded systems, and power management modules. Its maximum input voltage of 20V and low dropout voltage of 0.55V at full load allow it to operate with a wide range of input voltages, reducing the need for external components and improving system efficiency.
Another notable feature of the TL1963A-25KTTR is its high PSRR (power supply rejection ratio) of 63dB at 120Hz, which helps reduce noise and ripple in the output voltage caused by the input voltage variations. This is particularly important in sensitive applications that require low noise and high accuracy, such as medical devices, audio equipment, and instrumentation.
The TL1963A-25KTTR also includes several protection features that make it a robust and reliable solution for demanding applications. Its enable control pin allows for easy on/off control of the output voltage, while its over-temperature and reverse-polarity protection ensure safe operation and prevent damage to the device and the circuitry. With an operating temperature range of -40°C to 125°C, the TL1963A-25KTTR can operate reliably in harsh environments and extreme conditions.
In terms of packaging, the TL1963A-25KTTR comes in a compact and easy-to-mount TO-263-6 package with five leads and a tab, making it suitable for surface-mount applications. Its DDPAK/TO-263 configuration provides excellent thermal performance, allowing for high current capability and reliable operation.
In conclusion, the TL1963A-25KTTR is a versatile and high-performance linear regulator that provides a stable and reliable power supply for a wide range of applications. Its low dropout voltage, high output current, and excellent line and load regulation make it a suitable choice for demanding applications that require high accuracy and low noise. Its compact package, protection features, and wide operating temperature range make it a flexible and robust solution for industrial, automotive, medical, and consumer applications.
