Description

The MST53XXB 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, 2.5, 3.0, 3.3, 3.6, 4.0, 4.2 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.
