ST has shipped billions of voltage regulators into commercial, industrial and automotive applications.

Our RobuST product range includes a range of LDO voltage regulators with 5 V output and up to 500 mA load-current capability. A PMOS-transistor pass element guarantees a very low maximum dropout voltage of 500 mV and low quiescent current.  They embed additional features such as reset, watchdog and enable pins, together with short-circuit and thermal protection.
