... Application Hints Like any low dropout regulator, SE5218 requires external capacitors to ensure stability. external capacitors must be carefully selected to ensure performance. Input Capacitor An input capacitor of at least 1μF is required. The inexpensive Electrolytic capacitor is preferred. The value can be increased without upper limit. Output Capacitor An output capacitor is required for stability ...
