Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency PCB design, such as using a solid ground plane, minimizing trace lengths, and using vias to connect signals to the ground plane.
To ensure stability, follow the recommended component values and PCB layout, and make sure to decouple the input and output pins properly. Additionally, check that the output capacitor is sufficient to filter out high-frequency noise and that the feedback resistors are properly sized.
The maximum input voltage is 6V, but it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V to ensure optimal performance and reliability.
The LM9036QMM-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliability and prevent thermal shutdown.
Use a oscilloscope to measure the output voltage and input voltage, and check for signs of oscillation or noise. Also, verify that the input and output capacitors are properly sized and that the feedback resistors are correctly valued. If issues persist, consult the datasheet and application notes for troubleshooting guidance.
