... With the primary output disabled, quiescent current drain is typically 100µA when supplying 100µA from the secondary output. The CS8391 is extremely robust with protection provided for reverse battery, short circuit, and overtemperature on both outputs. The CS8391 is available in a 5-lead 2 D PAK. Primary Output V OUT 1 * ...

... General The CS8391 is a micropower dual 5V regulator. All bias required to operate the internal circuitry is derived from the standby output this output experiences an OUT2 over current situation and collapses, then V collapse (see timing diagrams). If there is critical circuitry that must remain active under most conditions it should be connected to V cuitry that is likely to be subjected to a short circuit, e ...
