The S-1172 series uses CMOS technology to develop a positive voltage regulator with ultra-low step-down, high-precision output voltage and low current consumption. The S-1172 series offers very low step-down and large output current due to the low on-resistance of the built-in transistor.
Block Diagram
The S-1172 series includes an overcurrent protection circuit to prevent the load current from exceeding the current capacitance of the output transistor, a heat shutdown circuit to prevent damage due to overheating, and an inrush current limiting circuit to limit excessive inrush current generated when powered on.
The ON/OFF circuit ensures longer battery life. There are a wide variety of capacitors, including small ceramic capacitors, compared to voltage regulators using traditional CMOS technology. High thermal radiation HSOP-6 and small size SOT-89-5 packages enable high density installation.
