The S-13A1 Series is a positive voltage regulator with a low dropout voltage, high-accuracy output voltage, and low current
consumption developed based on CMOS technology.
A 2.2
μF
small ceramic capacitor can be used, and the very small dropout voltage and the large output current due to the
built-in transistor with low on-resistance are provided. The S-13A1 Series includes a load current protection circuit that
prevents the output current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that
prevents damage due to overheating. In addition to the types in which output voltage is set inside the IC, a type for which
output voltage can be set via an external resistor is added to a lineup. Also, the S-13A1 Series includes an inrush current
limit circuit to limit the excess inrush current generated at power-on or at the time when the ON / OFF pin is set to ON. High
heat radiation HSOP-8A and HSOP-6 or small SOT-89-5 and HSNT-6A packages realize high-density mounting.
