5. Examples of Performance Curves When Ceramic Capacitors Are Used
The stable operating area (SOA) is an area where the output voltage does not go into oscillation. The
following figures represent the SOA obtained using an evaluation circuit shown below. The SOA is determined
by the equivalent series resistance (ESR) of the output capacitor and the output current. The TAR5SxxU
provide stable operation even when a ceramic capacitor is used as the output capacitor.
If the ripple frequency is 30 kHz or greater, the ripple rejection characteristics differ, depending on the type
of the output capacitor (ceramic or tantalum) as shown by the bottom figure on this page.
It is recommended to verify that TAR5SxxU operate properly under the intended conditions of use.
