The recommended input voltage range for the LM385D-1-2 is 4.5V to 40V. Operating the device outside of this range may affect its performance and accuracy.
To ensure the output voltage of the LM385D-1-2 remains stable over temperature, it is recommended to use a bypass capacitor (e.g., 10uF) between the input pin and ground, and to keep the device away from high-temperature sources.
No, the LM385D-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 typical output impedance of the LM385D-1-2 is around 10 ohms. This means that the device can drive a load current of up to 10mA, but the output voltage may droop slightly under heavy load conditions.
To protect the LM385D-1-2 from reverse voltage, it is recommended to add a diode (e.g., 1N4001-1N4007) in series with the input pin to prevent reverse voltage from damaging the device.
