The S24SP has efficiency up to 93%, the line regulation is ±0.2%, and output ripple & noise of 100mVp-p. Note that ripple & noise is measured with a bandwidth of 20 MHz with a 20 µF tantalum capacitor and a 1 µF ceramic capacitor. Those features are the strengths of S24SP series. Additionally, it is shorter in terms of height and also conforms to the additional railway safety certification of EN50155.
