LM1851M Frequently Asked Questions (FAQ)
-
The minimum input voltage required for the LM1851M to operate is 4.5V, but it's recommended to use a minimum of 5V to ensure proper operation and stability.
-
To ensure the output voltage is accurate and stable, it's recommended to decouple the input and output pins with capacitors (e.g., 10uF and 100nF respectively), and to use a low-ESR capacitor (e.g., 10uF) on the output pin to filter out noise and ripple.
-
The maximum output current that the LM1851M can supply is 10mA, but it's recommended to limit the output current to 5mA or less to ensure stability and accuracy.
-
During power-up, the LM1851M's output voltage may take some time to settle to its final value, typically around 10ms. During power-down, the output voltage will decay rapidly to zero. It's recommended to use a soft-start circuit or a voltage supervisor to ensure a clean power-up and power-down sequence.
-
No, the LM1851M 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 under varying input conditions or load currents.
