ABLIC S-13A1F10-U5T1U3

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 builtin 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 packages realize high-density mounting.

For types in which output voltage is internally set, the inrush current limit time can be changed via an external capacitor (Css). Inrush current limit time 0.7 ms typ. (Types in which output voltage is internally set, CSS = 1.0 nF); Inrush current limit time 0.4 ms typ. (Types in which output voltage is internally set, SSC pin = open); Inrush current limit time 0.4 ms typ. (Types in which output voltage is externally set)
