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, IN. Also, ensure that the input voltage is within the recommended range, and the EN pin is properly biased.
The DELAY pin is used to delay the output voltage ramp-up time. By connecting a capacitor from DELAY to GND, you can adjust the ramp-up time to prevent inrush currents and reduce electromagnetic interference (EMI). The recommended capacitor value is 10nF to 100nF.
The output voltage of the TPS3824-33DBVR is fixed at 3.3V. However, if you need to adjust the output voltage, you can use an external resistor divider network between the OUT and ADJ pins. The output voltage can be calculated using the formula: VOUT = 3.3V x (R1 / R2 + 1), where R1 and R2 are the resistors in the divider network.
The maximum output current of the TPS3824-33DBVR is 150mA. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. Be sure to check the datasheet for thermal derating and power dissipation calculations.
