Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common-mode choke or ferrite bead to filter out high-frequency noise.
To ensure stability, make sure to follow the recommended compensation network values and layout guidelines. Also, ensure that the output capacitor is of high quality and has a low equivalent series resistance (ESR). Additionally, avoid using long output traces and keep the output capacitor close to the IC.
The maximum input voltage of the LT1013DIDRE4 is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent damage to the internal components.
The LT1013DIDRE4 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation. Additionally, ensure that the PCB and surrounding components are also rated for high-temperature operation.
To troubleshoot issues, start by checking the input voltage, output voltage, and output current. Use an oscilloscope to check for oscillations or noise on the output. Also, check the PCB layout and ensure that it follows the recommended guidelines. If the issue persists, consult the Texas Instruments support resources or contact their technical support team.
