55V CST75XX series

    The CST7550 series is ahighvoltage,ultralow-power,low dropout voltage regulator. 

    The device can deliver 350mA output current with a dropout voltage of 350mV and allows an input voltage as high
as 55V. The typical quiescent current is only 2µA. The device is available in fixed output voltages of 1.8,2.5,2.8,3.0,3.3,3.6,4.0,4.2,4.4 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.
