The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of LM293N, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
LM293N Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM293N is 26V, but it's recommended to keep it below 20V for reliable operation.
-
To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.
-
The minimum input voltage required for the LM293N to regulate properly is 7.5V for the 5V output version, and 10.5V for the 12V output version.
-
The LM293N is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Derating is required for high-temperature operation.
-
The power dissipation of the LM293N can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
