The 78SR100 is a series of wide input voltage, 3-terminal Integrated Switching Regulators (ISRs). These ISRs have a maximum output current of 1.5A and an output voltage that is laser trimmed to a variety of industry standard voltages. These 78 series regulators have excellent line and load regulation with internal short-circuit and over-temperature protection, are very flexible, and may be used in a wide variety of applications.
The 78SR100 series integrated switching regulators provide up to 1.5 A of output current with efficiencies greater than 85 % and a very small footprint. They include internal short‑circuit and over‑temperature protection and operate over a wide input voltage range.
The document lists electrical characteristics, mechanical specifications, packaging options, and ordering information for the 78SR100 family, including detailed graphs of efficiency, ripple, and thermal derating.
