Product Summary

The PT5102A is an economical, easy-to-use 1-A positive step-down, Integrated Switching Regulator (ISR). The PT5102A is compatible with most TO-220 style linear regulators, and when employed as a linear replacement, provide significant benefits in both efficiency and power dissipation. The PT5102A is recommended for use in a wide variety of on-board power regulation applications. These include computer, data storage, industrial controls, and battery powered equipment. Modules are laser-trimmed for optimal output voltage accuracy, and exhibit excellent line and load regulation. The PT5102A also features output current limiting and thermal shutdown protection.
