CST75XX Description:
The CST75XX 36V series is a high voltage,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 shortcircuit and thermal shutdown protection.Although designed primarily as fixed voltage regulators, the device can be used with external components to obtain variable voltages.
