PRODUCTION DATA
From Table 7-4, the TLVM1440x requires a minimum of 24µF of effective output capacitance for proper operation at an output voltage of 5V at 1MHz and requires a minimum of 37µF of effective output capacitance for proper operation at an output voltage of 3.3V at 1MHz. Use high-quality ceramic type capacitors with sufficient voltage and temperature rating. If needed, connect additional output capacitance to reduce ripple voltage or for applications with specific load transient requirements.
For this design example, use two 22µF, 25V rated, X7R, 1210, ceramic capacitors connected close to the module from the VOUT1 to PGND and two 22µF, 25V rated, X7R, 1210, ceramic capacitors from the VOUT2 pins to PGND. Use the derating curves from the capacitor data sheet to gauge the effective capacitance by temperature and DC bias.
