TI recommends low-ESR ceramic capacitors for output capacitors. There is a requirement for minimum capacitance on the output of the LMZM23601 to ensure stable operation. The minimum output capacitance requirement depends on the output voltage setting. There is also a maximum capacitance value for stability and to limit the in-rush supply current. Excessive output capacitance can result in excessive current to be drawn from the input supply during startup. If the overcurrent condition is persistent during start-up, the over current protection of the LMZM23601 can activate and affect the normal output voltage ramp up. In extreme cases, the Section 7.3.5 operation can be activated during start-up if the maximum output capacitance is exceeded.
Refer to Table 8-3 for the minimum, recommended, and maximum output capacitance values for each output voltage. For this example with a 5-V output a 22-μF capacitor can be used.
