PT5107S [Texas Instruments]

The PT5100 modules are a series of economical, easy-to-use 1-A positive step-down, Integrated Switching Regulators (ISRs). These ISRs are compatible with most TO-220 style linear regulators, providing significant benefits in efficiency and power dissipation. They feature laser-trimmed output voltage for optimal accuracy, excellent line and load regulation, output current limiting, and thermal shutdown protection. Key advantages include 90%+ efficiency, internal short-circuit protection, pin-compatibility with 3-terminal linear regulators, over-temperature protection, small footprint, wide input range, and 5-pin mount options.
