Image of ABLIC S-19259 Series Linear Regulators The ABLIC S-19259 is a positive voltage regulator developed with CMOS technology that features low-voltage operation, a highly accurate output voltage, and a high output current. It provides a very small dropout voltage and a large output current due to a built-in transistor with low on-resistance and can be used with a small 1.0 µF ceramic capacitor. This IC also includes an overcurrent protection circuit that prevents the load current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that prevents damage due to overheating.
