7.3.5 Output Capacitor Selection

The minimum required and maximum output capacitance of the LMZ36002 is a function of the output voltage as shown in Table 6. Additionally, the output voltage will determine the Versa-Comp configuration (see VERSA-COMP Pin Configurations), which is also included in Table 6. The capacitance values listed in Table 6 are the specified capacitance values. The effects of DC bias and temperature variation must be considered when using ceramic capacitance. For ceramic capacitors, package size, voltage rating, and dielectric material will contribute to differences between the specified value and the actual effective value of the capacitance. COUT(min) must be comprised of ceramic type capacitors. Additional capacitance, not exceeding COUT(max), may be ceramic type or low-ESR polymer type. See Table 7 for a preferred list of output capacitors by vendor.

Table 6. Required Output Capacitance

VOUT (V) MINIMUM REQUIRED COUT (µF) (1)(2) MAXIMUM COUT (µF) (2) Versa-Comp Connection
2.5 64 350 Leave OPEN
3.3 64 350 Connect to VADJ
5.0 64 350 Connect to VADJ
6.0 64 200 Connect to VADJ
7.5 100 200 Connect to VADJ
(1) Minimum required output capacitance must be comprised of ceramic capacitance.
(2) COUT values represent specified capacitance values.
