The S-817 Series is a 3-terminal positive voltage regulator, developed using CMOS technology. Small ceramic capacitors can be used as the output capacitor, and the S-817 series provides stable operation with low loads down to 1 µA. Compared with the conventional voltage regulator, it is of low current consumption, and with a lineup of the super small package (SNT-4A:1.2 x 1.6mm). It is optimal as a power supply of small portable device.
The S-817 series provides a 3‑terminal positive voltage regulator built with CMOS technology. It is designed for battery‑powered devices, personal communication equipment and small portable appliances, and can operate with ultra‑low loads down to 1 µA.
The series is offered in several compact packages (SNT‑4A, SC‑82AB, SOT‑23‑5, SOT‑89‑3, TO‑92) and includes detailed pin configurations, absolute maximum ratings, and performance specifications such as low dropout voltage and short‑circuit protection.
