Automotive High-Voltage LDO: IM6L4x20 & IM6L4x50

Immorta's IM6L4x20 and IM6L4x50 series are high-efficiency, reliable automotive-grade integrated voltage regulators (LDO). As an ideal automotive power-management solution, Immorta's LDO supports input voltage up to 40 V, connecting directly to the automotive battery and meeting stringent automotive application requirements. Its low-power design and wide current-load range (0–500 mA) improve power-management reliability while effectively reducing energy consumption. This means whether during vehicle start-up or long-term operation, Immorta's LDO provides stable, long-lasting power supply, delivering a high-reliability, low-energy-consumption experience — an ideal choice for modern automotive power-management needs.
