STMicroelectronics provides a recommended PCB layout in the application note AN2352, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The ST2129BQTR has a programmable output voltage range. You can configure it using the VSEL pins, which select the output voltage range. The datasheet provides a table that shows the VSEL pin configurations for different output voltage ranges. Additionally, you can use the STMicroelectronics' voltage regulator selection tool to help with the configuration.
The ST2129BQTR has a maximum input voltage rating of 18V. However, it's recommended to operate the device within the specified input voltage range of 4.5V to 15V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended capacitor selection and placement guidelines provided in the datasheet. Additionally, you should ensure that the input voltage is within the specified range, and the device is operated within the recommended temperature range.
The thermal shutdown temperature of the ST2129BQTR is typically around 150°C. When the device temperature exceeds this threshold, it will shut down to prevent damage. The device will automatically restart when the temperature drops below 130°C.
