The typical output impedance of the LM185H-1.2 is around 0.2 ohms, which is relatively low and makes it suitable for applications where a low-impedance voltage reference is required.
When the input voltage is below the minimum recommended value of 4.5V, the LM185H-1.2 may not regulate properly, and the output voltage may not be accurate. It's recommended to ensure that the input voltage is above the minimum recommended value to ensure proper operation.
No, the LM185H-1.2 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it's not intended to regulate the output voltage to a specific value. If you need a voltage regulator, you should use a separate device, such as the LM317 or LM338.
The LM185H-1.2 has a temperature coefficient of around 10ppm/°C, which means that the output voltage will change by around 10ppm (0.0012%) for every 1°C change in temperature. This is relatively low and makes the LM185H-1.2 suitable for applications where high accuracy is required over a wide temperature range.
Yes, the LM185H-1.2 is a high-reliability device that is suitable for use in aerospace and other high-reliability applications. It's built with high-quality materials and has undergone rigorous testing to ensure its reliability and performance.
