General Description

The MA3053 series is a high voltage, ultralow-power, low dropout voltage regulator. The device can

deliver 100mA output current with a dropout voltage of 300mV and allows an input voltage as high as

35V. The typical quiescent current is only 1.6μA. The device is available in fixed output voltages of 1.8,

3.0, 3.3 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.
