LM2937ES-15 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2937ES-15 is 26V, but it's recommended to keep it below 24V for reliable operation.
-
The LM2937ES-15 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.
-
The power dissipation of the LM2937ES-15 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.
-
The minimum input voltage required for the LM2937ES-15 to regulate the output voltage is around 17V, but it's recommended to keep it above 18V for reliable operation.
-
The LM2937ES-15 is a linear voltage regulator, not a switching regulator. It's not suitable for switching power supply designs. Instead, consider using a switching regulator like the LM2675 or LM5005 from Texas Instruments.
