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.
