LM2903D Frequently Asked Questions (FAQ)
-
The maximum input voltage for the LM2903D is 26V, but it's recommended to keep it below 25V for reliable operation.
-
The LM2903D is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
-
To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and keep the input capacitance below 10uF.
-
No, the LM2903D is a linear voltage regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-power applications.
-
The minimum input voltage required for the LM2903D to regulate the output voltage is typically 2.5V above the output voltage (e.g., 7.5V for a 5V output).
