Rev.1.1_00 HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR www.datasheet4u.com S-1172 Series The S-1172 Series, developed based on CMOS technology, is a positive voltage regulator with a super low dropout voltage, high output voltage accuracy, and low current consumption. The S-1172 Series provides the very small dropout voltage and the large output current due to the built-in transistor with low on-resistance. The overcurrent protector prevents the load current from exceeding the capacitance of output transistor. The thermal shutdown circuit prevents damage caused by heat, the rush current control circuit limits the excessive rush current during start-up. The ON/OFF circuit ensures longer battery life.
