S-1133 Series HIGH RIPPLE-REJECTION AND LOW DROPOUT www.ablic.com MIDDLE-OUTPUT CURRENT CMOS VOLTAGE REGULATOR www.ablicinc.com ABLIC Inc., 2006-2015 Rev.3.1 02 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. *1 A 1 F small ceramic capacitor can be used . It operates with low current consumption of 60 A 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-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 F or more can be used for products whose output voltage is 1.7 V or less. Features Output voltage (internally set): 1.2 V to 6.0 V, selectable in 0.1 V step. Output voltage (externally set): 1.8 V to 8.2 V, settable via external resistor (S-1133B00/S-1133A00) Input voltage: 2.0 V to 10 V Output voltage accuracy: 1.0% (1.2 V to 1.4 V output product: 15 mV) Dropout voltage: 130 mV typ. (3.0 V output product, I = 100 mA) OUT Current consumption: During operation: 60 A typ., 90 A max. During power-off: 0.1 A typ., 1.0 A max. *1 Output current: Possible to output 300 mA (V V 1.0 V) IN OUT(S) Input and output capacitors: A ceramic capacitor of 1.0 F or more can be used. (A ceramic capacitor of 2.2 F or more can be used for products whose output voltage is 1.7 V or less.) Ripple rejection: 70 dB typ. (1.2 V output product, f = 1.0 kHz) Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in thermal shutdown circuit: Prevents damage caused by heat. Built-in ON / OFF circuit: Ensures long battery life. Operation temperature range: Ta = 40C to 85C *2 Lead-free, Sn 100%, halogen-free *1. Attention should be paid to the power dissipation of the package when the output current is large. *2. Refer to Product Name Structure for details.
