BUILT-IN HIGH-ACCURACY VOLTAGE DETECTOR AND RESET INPUT FUNCTION
© SII Semiconductor Corporation, 2008-2015
Rev.2.2_01
The S-1702 Series, developed based on CMOS technology, is a 150 mA output positive voltage regulator with a low
dropout voltage, a high-accuracy output voltage, and low current consumption.
The S-1702 Series includes a voltage regulator with high-accuracy output voltage of ±1.0% allowing to use a ceramic
capacitor of 1.0 μF or more, and a voltage detector that monitors the output/input voltage of the regulator. It also includes
an overcurrent protection circuit that prevents the output current from exceeding the current capacitance of the output
transistor and an output forcible discharge circuit for the regulator operation off.
Small SNT-6A package is available for the S-1702 Series. And an external small capacitor can be used, enabling
high-density mounting. Its super-low current consumption makes the S-1702 Series ideal for mobile devices.
