LM293AD Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM293AD is 26V, but it's recommended to keep it below 24V for reliable operation.
-
Yes, the LM293AD can be used as a voltage regulator for a microcontroller, but it's essential to ensure that the output voltage and current meet the microcontroller's requirements.
-
The output voltage of the LM293AD can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.235V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
-
The minimum input voltage required for the LM293AD to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
-
The LM293AD is rated for operation up to 125°C, but it's essential to ensure that the device is properly heat-sinked and that the junction temperature is kept below 150°C to prevent damage.
