ABLIC S-1133B31-U5T1U

The S-1133 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption (300 mA output current) developed based on CMOS technology. A 1 μF small ceramic capacitor can be used. It operates with low current consumption of 60 μA typ. The S-1133 Series includes an overcurrent protection circuit that prevents the output current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that prevents damage due to overheating. In addition to the types in which output voltage is set inside the IC, a type for which output voltage can be set via an external resistor is added to a lineup (S-1133×00 Series). SOT-89-5 and super-small SNT-8A packages realize high-density mounting. This, in addition to low current consumption, makes the S-1133 Series ideal for mobile devices.
