DESCRIPTION
MAS9122 is a three output voltage regulator. It is designed for three different output voltages, which can be modified through a mask option. Regulators operating mode is controlled by two enable/disable pins. The circuit consists of a bandgap voltage reference, an error amplifier, a current limit circuit and a thermal protection circuit.
