A Ultralow Quiescent Current, Fast Transient and
Low Dropout Voltage Regulator
⏹ Description
The MST53XX ries 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 ud with external components to obtain variable voltages.
