STMicroelectronics ST732 28V Low-Dropout Regulators
STMicroelectronics ST732 28V Low-Dropout (LDO) Regulators feature an ultra-low 5µA quiescent current (IQ), making them ideal for applications permanently connected to a power supply or battery. The low IQ is also useful for electronic modules that remain permanently on. The ST732 features integrated protection functions, including current limit, short-circuit, and thermal shutdown. STMicroelectronics ST732 28V Low-Dropout (LDO) Regulators feature an extended input voltage range, very low drop voltage, and low quiescent current of these devices, making them suitable for low-power after-market automotive and consumer applications.Features
