STMicroelectronics provides a recommended PCB layout in the application note AN2663, which includes guidelines for component placement, routing, and grounding to minimize EMI and noise.
The value of RSET depends on the desired output voltage and the input voltage range. STMicroelectronics provides a calculation formula in the datasheet, and a more detailed explanation can be found in the application note AN2663.
Although the datasheet specifies a maximum input voltage of 18V, STMicroelectronics recommends limiting the input voltage to 15V to ensure reliable operation and prevent damage to the device.
LY510ALH is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. STMicroelectronics recommends derating the output current and voltage according to the temperature derating curve provided in the datasheet.
To ensure output voltage stability, it's essential to follow the recommended PCB layout, use a suitable output capacitor, and ensure that the input voltage is within the specified range. Additionally, the application note AN2663 provides guidelines for optimizing the output voltage stability.
