The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input voltage ripple and improve overall system stability.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 100nF capacitor between the FB pin and GND. Additionally, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
The maximum output current of the TPS3820-33DBVR is 150mA. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. Always check the datasheet for the recommended operating conditions and thermal derating.
The TPS3820-33DBVR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Always check the datasheet for the recommended operating temperature range and thermal derating.
The output voltage of the TPS3820-33DBVR can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage. Always follow the datasheet guidelines for setting the output voltage.
