    Products Detail

    The PT78ST100 series are 1.5A positive step-down integrated switching regulators with a very small footprint and high efficiency (>85%). They feature self-contained inductor, internal short-circuit protection, over-temperature protection, and fast transient response. The output voltage is laser trimmed to industry standard voltages (5.0V, 5.1V, 5.25V, 6.0V, 6.5V, 7.0V, 8.0V, 9.0V, 10.0V, 12.0V, 13.9V, 15.0V). These regulators have excellent line and load regulation and are very flexible for a wide variety of applications. They require a 100µF electrolytic or tantalum output capacitor for proper operation.
