Product Information

Rev.2.1_00 HIGH RIPPLE-REJECTION AND LOW DROPOUT MIDDLE-OUTPUT CURRENT CMOS VOLTAGE REGULATOR www.datasheet4u.com S-1133 Series 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*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 packages realize 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. Features • Output voltage : • Voltage setting via external resistor : • Input voltage range : • High-accuracy output voltage : • Low dropout voltage : • Low current consumption : • Output current : • Low ESR capacitor can be used : 1.2 to 6.0 V, selectable in 0.1 V steps. Selectable from 1.8 to 8.2 V (S-1133B00/S-1133A00) 2.0 to 10 V ±1.0% accuracy (1.2 to 1.4 V output product : ±15 mV accuracy) 130 mV typ. (3.0 V output product, IOUT = 100 mA) During operation : 60 µA typ., 90 µA max. During shutdown : 0.1 µA typ., 1.0 µA max. 300 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1 A ceramic capacitor of 1.0 µF or more can be used for the input and output capacitors. (A ceramic capacitor of 2.2 µF or more can be used for products whose output voltage is 1.7 V or less.) 70 dB typ. (at 1.0 kHz, VOUT = 1.2 V) Overcurrent of output transistor can be restricted. Prevents damage due to overheating. Ensures long battery life.
