Texas Instruments recommends a star-ground configuration, with the analog and digital grounds separated and connected at a single point near the LM1036M. Additionally, keep the input and output traces short and away from noise sources, and use a solid ground plane to reduce electromagnetic interference.
To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Additionally, check that the output capacitor is properly sized and that the feedback resistors are within the recommended range. If oscillations occur, try adding a small capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
While the datasheet specifies a maximum input voltage of 12V, it's recommended to limit the input voltage to 10V to ensure reliable operation and prevent damage to the internal components.
The LM1036M is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to derate the output current and voltage according to the temperature derating curve in the datasheet, and consider using a heat sink or thermal management system to keep the device within its recommended operating temperature range.
Start by checking the input voltage, output voltage, and output current to ensure they are within the recommended ranges. Verify that the feedback resistors and output capacitor are properly sized and connected. Use an oscilloscope to check for oscillations or noise on the output, and consult the datasheet and application notes for troubleshooting guides and common pitfalls to avoid.
