36V CST75XX系列

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

     The device can deliver 150mA output current with a dropout voltage of 300mV and allows an input voltage as high as 36V. The typical quiescent current is only 1.5µA. 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.
