Cyp7903 Sot89-3L E Meter Current 1A High Voltage 40V Low Power Ldo Regulator IC

General DescriptionThe CYP7903 series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and laser trimming technologies. The CYP7903 consists of a high-precision voltage reference, an error amplification circuit, and a current limited output driver. Transient response to load variations have proved in comparison to the existing series.
