LM2903DRG4 Frequently Asked Questions (FAQ)
-
The maximum input voltage for the LM2903DRG4 is 26V, but it's recommended to keep it below 24V for reliable operation.
-
The LM2903DRG4 is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
-
Use a high-quality output capacitor (e.g., 10uF ceramic) and ensure the input capacitor (e.g., 1uF ceramic) is properly sized to minimize input ripple. Also, keep the output voltage sensing pin (VSENSE) close to the output capacitor.
-
A minimum of 1uF ceramic capacitor is recommended between the input pin and ground to ensure stability and reduce input ripple.
-
The LM2903DRG4 has a relatively high dropout voltage (around 2V), so it's not suitable for low-dropout applications. Consider using a low-dropout regulator like the TLV703 or TPS63050 instead.
