LP38690DT-3.3/NOPB Frequently Asked Questions (FAQ)
-
The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce output voltage ripple and improve transient response.
-
The LP38690DT-3.3/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation. Consult the datasheet for thermal derating curves and guidelines.
-
To ensure stability, follow the recommended PCB layout guidelines, use a sufficient input capacitor, and ensure the output capacitor is within the recommended range (10uF to 100uF). Additionally, avoid using long, thin traces and minimize parasitic inductance.
-
Yes, the LP38690DT-3.3/NOPB is suitable for powering microcontrollers. However, ensure the output voltage and current meet the microcontroller's requirements, and consider adding additional capacitors and filtering as needed to meet the microcontroller's power supply noise requirements.
-
The typical dropout voltage of the LP38690DT-3.3/NOPB is around 1.2V to 1.5V, depending on the output current. This means the input voltage should be at least 1.2V to 1.5V higher than the output voltage to ensure proper regulation.
