The S-19701 Series, developed by using CMOS technology, is a positive voltage regulator with a current monitoring function for 125°C automotive operation.
It provides an output current of 600 mA min., and a ceramic capacitor of 4.7 µF or more can be used as the output capacitor.
Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be controlled as the small value 15 µA typ.
The current monitor monitors the current flowing to the voltage regulator and outputs the voltage according to the external resistance, and limits the current value from exceeding the set value.
The S-19701 Series has two types of products of which one is the externally set product whose output voltage is determined by the external divided-resistor, and the other is the internally set product which includes an INT pin and whose output voltage is fixed. By connecting the VADJ pin to GND, the externally set product can be utilized as a high side switch with a current monitor.
