A regulator circuit is provided for use with cell plate voltage generators of memory cell capacitors and precharge bit lines voltage generators in semiconductor memories. The circuit employs a current source coupled to the charging reference voltage whose output is controlled by a level detector, which receives as input a reference level signal and the cell plate voltage. When the cell plate voltage drops below the reference level, the level detector triggers the current source, thereby recovering the cell plate voltage to the reference level. The level detector can be disabled through an input.
