The recommended connections to the LDO Regulators are illustrated in Figure 92.
Figure 92 LDO Regulators External Components
When selecting suitable capacitors, is it imperative that the effective capacitance is within the
required limits at the applicable input/output voltage of the converter. Ceramic X7R or X5R types are
recommended.
Wolfson recommends the following external components for use with LDO Regulators 1, 2, 3 and 4.
Note that larger capacitors will improve load transient response and power supply rejection. A
maximum of 10 μ F is possible at the output; a maximum of 1 μ F is possible at the input.
