Please contact each Web shop for details such as availability of online samples.

The S-1315 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 200 mA output current which has low dropout voltage, high-accuracy output voltage and low current consumption. The S-1315 Series enables high density mounting due to output capacitor-less.
The current consumption is extremely low as 7 μA typ., and even without an output capacitor, it realizes high-speed response.
It also has high-accuracy output voltage of ±1.0%.
