The S-19255 Series, developed by using CMOS process technology, is a positive voltage regulator with high-accuracy output voltage. This IC has high ripple-rejection of 80 dB typ.
Also, a built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. In addition to the conventional small package SOT-23-5, the super-small package HSNT-4(1010)B is added to the lineup, which realizes higher-density mounting.
