Infineon launched two new voltage regulator families targeting automotive applications. New products offer wide input voltage range (2.75V to 40) and very low quiescent 5µA - 40µA (e.g. for systems connected permanently to battery). Its new loop concept combines fast regulation and very good stability requiring only one small ceramic output capacitor of 1µF.
Voltage Regulators
Requirement Flow
Both families are designed to be operational in harsh automotive environment and implement automotive specific feature sets. To improve further stability and robustness products were designed and tested with LV124 requirements flow, which is unique and helps to improve quality in the field and minimize design effort and cost.
