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 is a family of 1.5 A, three‑terminal integrated switching regulators (ISRs) with a very small footprint. They offer high efficiency (>85 %), internal short‑circuit and over‑temperature protection, and can operate from a wide input voltage range, making them suitable for many applications.
The datasheet includes pin‑out information, suggested board layout, detailed electrical characteristics, thermal derating curves, and mechanical specifications such as package type (vertical or surface mount) and operating limits.
