S-13A1 Series www.ablic.com 5.5 V INPUT, 1000 mA VOLTAGE REGULATOR ABLIC Inc., 2011-2018 Rev.2.2 00 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 F 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.

Ripple rejection: 70 dB typ. (f = 1.0 kHz) Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in thermal shutdown circuit: Prevents damage caused by heat. Built-in inrush current limit circuit: Limits excessive inrush current generated at power-on or at the time when the ON / OFF pin is set to ON.
