The TI-TPS37F.pdf is a data sheet for the TPS37x, a high-voltage (65 V) linear regulator designed by Texas Instruments. This regulator is ideal for a wide range of applications where a stable voltage output is required, such as industrial power supplies, battery chargers, motor drives, and instrumentation. The TPS37x series includes several different models, each with its own set of features and specifications. These models are designed to provide a range of output options, including fixed voltage outputs as well as adjustable outputs using external resistors. One key feature of the TPS37x series is its high input voltage range of up to 65 V, making it suitable for use in systems with wide input voltage variations. This high input voltage range allows for flexibility in system design and power supply selection, and ensures reliable performance in harsh operating conditions. In addition to its high input voltage range, the TPS37x series also offers low dropout voltage, high output voltage accuracy, and excellent line and load regulation. These features make it an ideal choice for applications that require stable and precise voltage regulation, such as data acquisition systems, test and measurement equipment, and telecommunication infrastructure. The data sheet provides detailed specifications for each model in the TPS37x series, including input and output voltage ranges, dropout voltage, output current capability, and thermal performance. It also includes information on the device's packaging options, pinout diagram, and recommended operating conditions. Overall, the TI-TPS37F.pdf data sheet provides comprehensive information on the TPS37x series of high-voltage linear regulators, making it a valuable resource for engineers and designers looking to incorporate reliable voltage regulation into their systems.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under

Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.
