LM185H-1.2 Frequently Asked Questions (FAQ)

  • The typical operating temperature range for the LM185H-1.2 is 0°C to 70°C, but it can operate up to 125°C with reduced accuracy.

  • To ensure accurate and stable output voltage, make sure to decouple the input pin with a 10uF capacitor, use a low-ESR output capacitor, and keep the device away from high-current switching circuits.

  • No, the LM185H-1.2 is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage like a voltage regulator IC.

  • The LM185H-1.2 does not have a minimum load current requirement, but it is recommended to have a minimum load of 100uA to ensure accurate output voltage.

  • During power-up, the LM185H-1.2 output voltage may take some time to settle to its final value. During power-down, the output voltage will decay slowly due to the internal capacitors. It is recommended to add an external capacitor to ensure a clean shutdown.
