7.3.3 Output Capacitor Selection

The minimum amount of required output capacitance for the LMZM33606 varies depending on the output voltage. Table 3 lists the minimum output capacitance for several output voltage ranges. The required output capacitance must be comprised of all ceramic capacitors.

When adding additional output capacitance, ceramic capacitors or a combination of ceramic and polymer-type capacitors can be used. The required capacitance above the minimum is determined by actual transient deviation requirements. See Table 4 for a preferred list of output capacitors by vendor.

Table 3. Minimum Required Output Capacitance

VOUT RANGE (V) MINIMUM REQUIRED COUT(1)
MIN MAX CAPACITANCE VALUE VOLTAGE RATING
1 1 400 µF ≥ 6.3 V
> 1 1.8 300 µF
> 1.8 2.5 200 µF
> 2.5 3.3 150 µF
> 3.3 5 100 µF
> 5.0 12 100 µF ≥ 16 V
> 12 20 50 µF ≥ 25 V
(1) The minimum required output capacitance must be made up of ceramic type capacitors. Additional capacitance above the minimum can be either ceramic or low-ESR polymer type.
