A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor (CIN). This value provides a good balance between noise filtering and stability.
To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the IC, and use a low-ESR output capacitor. Additionally, ensure the feedback resistors (RFBT and RFBG) are properly selected and placed.
The maximum input voltage rating for the TPS61085DGKRG4 is 5.5V. Exceeding this voltage may damage the device or affect its performance.
The TPS61085DGKRG4 is rated for operation up to 125°C (TJ). However, the device's performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the device's specifications accordingly.
The output voltage (VOUT) can be calculated using the formula: VOUT = VREF * (1 + RFBT/RFBG), where VREF is the internal reference voltage (1.2V) and RFBT and RFBG are the feedback resistors.
