ABLIC S-19259 Voltage Regulators

ABLIC S-19259 Voltage Regulators are positive voltage regulators with a low voltage operation, high-accuracy output voltage, and high output current. These regulators are developed based on CMOS technology. A 1μF small ceramic capacitor can be used, and the built-in transistor with low on-resistance provides a very small dropout voltage and a large output current. The S-19259 ICs include an overcurrent protection circuit that prevents the load current from exceeding the current capacity of the output transistor. The voltage regulators also feature a thermal shutdown circuit that prevents damage due to overheating. The S-19259 regulators are ideal for automotive use, constant-voltage power supplies for electrical applications for vehicle interior, and constant-voltage power supplies for home electric appliances.
