LM1851N Frequently Asked Questions (FAQ)
-
The recommended output capacitor value is 10uF to 22uF, with a minimum ESR of 5 ohms to ensure stability and noise reduction.
-
No, the LM1851N 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.
-
To ensure stability and accuracy over temperature, it is recommended to use a thermally stable ceramic capacitor for the output capacitor, and to keep the device away from high-temperature sources. Additionally, the device should be operated within its specified temperature range.
-
Yes, the LM1851N can be used in high-impedance circuits, but it is recommended to add a buffer amplifier to isolate the voltage reference from the load to prevent loading effects.
-
The typical noise performance of the LM1851N is 10uVpp (peak-to-peak) from 0.1Hz to 10Hz, and 1uVrms (root mean square) from 10Hz to 100kHz.
