GENERAL DESCRIPTION

The MA3054 series is a high voltage, ultralow-power, low dropout voltage regulator. The device can

deliver 350mA output current and allows an input voltage as high as 45V. The typical quiescent current is

only 2.1μA. The device is available in fixed output voltages of 1.8V, 3.3V and 5.0V. The device features

integrated short-circuit and thermal shutdown protection.

Although designed primarily as fixed voltage regulators, the device can be used with external

components to obtain variable voltages
