Silan SA1117 1A LDO Regulator Datasheet
The SA1117 is a positive‑voltage, low‑dropout three‑terminal linear regulator designed for 1 A output current. It is available in fixed‑output versions (1.5 V, 1.8 V, 2.5 V, 2.85 V, 3.0 V, 3.3 V, 5.0 V) and an adjustable version with 1 % voltage accuracy. Integrated over‑temperature and current‑limit circuitry makes it suitable for a wide range of electronic products such as handheld computers, battery chargers, and portable devices.
The datasheet provides electrical characteristics, pin descriptions, typical application circuits, and package dimensions for SOT‑89, SOT‑223, TO‑220, TO‑252, and TO‑263 packages. Key parameters include a 1.2 V dropout at 1 A, operating temperature from –40 °C to 125 °C, and recommended input voltage up to 20 V. This manual is written in Chinese.
