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 is a 3‑terminal positive voltage regulator built with CMOS technology. It operates with ultra‑low current consumption and can use small ceramic capacitors as the output capacitor, providing stable operation down to light loads.
Typical applications include power sources for battery‑powered devices, personal communication equipment, and small home electronic appliances. The series is offered in several compact packages such as SNT‑4A (1.2 × 1.6 mm), SC‑82AB, SOT‑23‑5, SOT‑89‑3 and TO‑92, making it suitable for portable and space‑constrained designs.
