SOT-89-5 (UP005-A)
SNT-8A (PH008-A)The S-1133 Series is a positive voltage regulator with a low dropout voltage (LDO), 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*1. 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 capacitance 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-1133x00 Series). SOT-89-5 and super-small SNT-8A package realizes a high density mounting. This, in addition to low current consumption, makes the S-1133 Series ideal for mobile devices. *1. A ceramic capacitor of 2.2 µF or more can be used for products whose output voltage is 1.7 V or less.
