LM293DRE4 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM293DRE4 is 26V, but it's recommended to keep it below 24V for reliable operation.
-
The LM293DRE4 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 voltage at high temperatures.
-
To ensure stability, use a minimum output capacitance of 10uF with an ESR of 0.05 ohms or less, and a minimum input capacitance of 10uF with an ESR of 0.1 ohms or less.
-
No, the LM293DRE4 is a positive voltage regulator and cannot be used to regulate a negative voltage. For negative voltage regulation, consider using a negative voltage regulator like the LM2991.
-
The minimum input voltage required for the LM293DRE4 to operate is 7.2V, but it's recommended to keep it above 8V for reliable operation.
