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

The S-1323 series is a positive voltage regulator with a low dropout voltage (LDO), high output voltage accuracy, and low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors. A small SC-82AB package realizes high-density mounting.
