Zusammenfassung:A retaining circuit includes: a low dropout regulator (LDO) circuit for generating a primary operation voltage, a secondary operation voltage generation (SOVG) circuit, and a memory circuit. The SOVG circuit generates a secondary operation voltage, and the memory circuit is powered by the secondary operation voltage to store at least one operation parameter, such that when the primary operation voltage is lower than a non-controlled level, the memory circuit holds the operation parameter to sustain operation.
