The SG117A/SG217A/SG317A series are three‑terminal positive adjustable voltage regulators offering improved performance over earlier designs. They provide a reference voltage tolerance of ±1 % and low line and load regulation, making them suitable for precision power supplies up to 1.5 A output current.
The datasheet includes absolute maximum ratings, thermal data, recommended operating conditions, electrical characteristics, characteristic curves, and application information such as bypass capacitor recommendations and connection diagrams. Ordering information for various package types (TO‑3, TO‑66, TO‑39, hermetic, etc.) is also provided.
| Maximum Output Current (K, R, IG packages) | 1.5 A |
|---|---|
| Reference Voltage Tolerance | ±1 % |
| Line Regulation | 0.01 %/V |
| Load Regulation | 0.3 % |
| Input‑to‑Output Voltage Differential | 40 V |
The reference voltage tolerance is ±1 %.
The maximum output current is 1.5 A.
A 0.1 µF bypass capacitor on the ADJUST pin is required.
Use a 1 µF tantalum or 25 µF electrolytic capacitor for input bypassing.
