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 proper power-up and initialization, make sure to follow the recommended power-up sequence: VCC, then EN, and finally, the input voltage. Also, ensure that the EN pin is properly biased to enable the device.
The maximum output current capability of the TPS3823-33DBVT is 150mA. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
To handle thermal considerations, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and avoid operating the device at high ambient temperatures or with high output currents for extended periods.
The DELAY pin is used to adjust the power-good delay time. By connecting a capacitor to this pin, you can adjust the delay time between the output voltage reaching its nominal value and the power-good signal being asserted.
