7.3.3 Output Capacitor Selection

The minimum amount of required output capacitance for the LMZM33604 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

V_OUT RANGE (V)		MINIMUM REQUIRED C_OUT⁽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.
