S-1155

S-1155 Series www.ablicinc.com © ABLIC Inc., 2007-2015 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR Rev.2.1_03 The S-1155 Series, developed by using CMOS technology, is a positive voltage regulator with a super low dropout voltage, high-accuracy output voltage and low current consumption. The S-1155 Series provides the very low dropout voltage and the large output current due to the built-in transistor with low on-resistance. The S-1155 Series includes an overcurrent protection circuit that prevents the load current from exceeding the current capacitance of the output transistor, a thermal shutdown circuit that prevents damage due to overheating, and an inrush current limit circuit to limit the excessive inrush current generated at power-on. The ON/OFF circuit ensures longer battery life. Compared with the voltage regulators using the conventional CMOS technology, a large variety of capacitors are available, including small ceramic capacitors The sma...
