The 78ST100 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 78ST100 series from Power Trends is a 1.5 A positive step‑down integrated switching regulator designed for compact applications. It offers high efficiency (>85 %), internal short‑circuit and over‑temperature protection, and a wide input voltage range.
The datasheet provides detailed specifications, pin‑out and ordering information, as well as package options and mechanical limits. For proper operation a 100 µF electrolytic or tantalum output capacitor is required.
